PREFACE
This book contains miscellaneous hydraulic information,
useful engineering tables and a complete table showing the
Flow of Water in WOOD PIPES of various sizes and under
varying heads. It is designed not only for the use of the
Engineer, but is also intended for a handy reference book for
the Mayor and his Council, the Water Superintendent, the
Irrigator, the Miner, in fact for anyone who has occasion to
divert water from its natural channel for the purpose of domestic
uses, power plants, irrigation, etc.
As a means of conveying water for all purposes, whether
the quantity be merely a few gallons a minute or hundreds of
cubic feet per second, WOOD PIPE is now conceded by advanced
engineers and experienced laymen to be an engineering and
economic success.
The flow of water in WOOD PIPE is greater, size for size,
than in pipe constructed of any other kind of material.
The flow tables herein given are based as far as possible
on results obtained by various experiments and may be assumed
to be as nearly correct as is required in a calculation of this
kind.
We have endeavored to make the tables in this book in
such simple form that they can be readily understood, and in
order to assist in such an understanding, examples and ex-
planations are given where necessary.

TEN REASONS FOR USING WOOD PIPE
1. It is preserved by water and not rusted or corroded
by it.
2. It is not corroded by sulphur, salt or mineral water and
fumes.
3. It is not destroyed by acids or salts.
4. Its carrying capacity is 20% greater than cast iron
pipe, and remains constant while metal pipe decreases with
age.
5. It does not taint or affect fluids going through it.
6. It does not burst when frozen. The elasticity of the
wood prevents bursting.
7. It requires less labor and experience to lay in place
than metal pipe.
8. It can be laid in shallower ditches than metal pipe, for
it is not easily affected by frosts.
9. It is cheaper than steel, wrought iron or cast iron pipe.
10. Its durability exceeds steel or wrought iron pipe, and is
classed with cast iron pipe.
We manufacture Pipe and Tanks from both Douglas Fir
and Redwood lumber, making a specialty of Fir at our Port-
land factory and Redwood at our San Francisco and Los
Angeles factories.

"A WORD TO ENGINEERS"
In locating wood pipe lines for irrigation, power plants,
city water systems, etc., there are several points that it would
be well for the engineer to consider carefully.
First — Pipe designed for heavy pressure requires a greater
amount of metal than low pressure pipe thereby increasing
the cost; but, in running out a ditch line, it is frequently more
economical to run across a valley, gulley or even a slight
depression with an inverted syphon rather than follow the
contour with a ditch.
Second — As has been shown by years of experience, the life
of wood pipe is materially prolonged by the saturation of the
staves, we, therefore, deem it good engineering practice, in
all cases where conditions will permit, to drop the grade of
the pipe as quickly as possible from the intake to a grade of
25 feet, or nearly, beneath the hydraulic grade line. This
insures a pipe constantly full of water and the saturation of
the top staves as well as the bottom, under pressure, while at
the same time it does not affect the quantity of metal and
therefore does not increase the cost.
Third — At all summits in the pipe line air valves, or vents,
should be placed. These may consist of automatic devices,
a number of which are on the market and have proven satis-
factory; or, if the pipe location is on side hill, a pipe of sufficient
diameter may be laid up the hill to an elevation slightly above
the hydraulic grade line, or, where necessary, above the line
of static pressure.
It is especially important that an air vent be placed at the
point where the pipe drops with increased gradient to reservoir
or power plant so that, in case more water be drawn off at the
outlet than the light gradient above can supply, a vacuum
will not be caused and collapse of the pipe will thus be averted.
Fourth — In determining the pressure head for which a wood
pipe shall be banded, ample allowance should be made for
water hammer or surge due to pumping or rapid closing of
valves. The factor of safety should be based on the maximum
PACIFIC TANK & PIPE COMPANY 9
pressure to which the pipe can possibly be subjected. For
example — a pumping line having a 45-foot lift or static head,
may have a friction head of 15 feet and a possible additional
head of 20 feet due to water hammer. The pipe in this case
should be banded for 80-foot head.
Fifth— In drawing specifications remember that manu-
facturers have standard forms of construction that have been
approved by engineers of ability and great experience. A
deviation from standard means, usually, an increased cost and,
most frequently, a product of inferior quality.
We procure for our pipe the best lumber that grows and is
handled in the lumber market. The most carefully and rigidly
drawn specifications cannot improve its quality.
The same is true of our other materials, steel rods, galvan-
ized wire, cast iron, etc. They are manufactured of the best
quality of raw material and are finished in the most suitable
manner for the purpose for which they are intended.
As specifications on all materials are more or less subject
to change we do not print them in this book, but for any specific
project we will gladly furnish specifications upon request.
Sixth— While the PACIFIC TANK & PIPE COMPANY is
essentially a manufacturing organization, we do, however, in
order to insure satisfaction to our customers, undertake to
construct Continuous Stave Pipe in place or to lay Machine
Banded Pipe in place under certain conditions, which are as
follows:
The purchaser agrees to unload material from
the cars, sort, haul and distribute the same along
the line of the trench in the manner directed by
us, do all trenching, backfilling, furnish and erect
all trestles or structures other than pipe.
We furnish all material f. o. b. cars at point of
delivery and construct the pipe in place under
contract, or furnish the material as above and
an experienced man to superintend the construc-
tion work at a price per diem.

DEFINITIONS
For illustration of definitions see cuts on opposite page.
The following definitions are not, on account of space,
sufficiently comprehensive to satisfy the requirements of the
practicing engineer. They will, however, be of interest to
those who have neither the time nor the inclination to study,
more deeply, the mysteries of hydraulics.
HEAD. — The word Head as applied to pipe lines has a
variety of meanings and is sometimes carelessly used by
engineers and laymen. The several meanings are classified
and described in the following ways:
STATIC HEAD.— The Static Head is the difference in
elevation between the surface of the water at the intake and
the elevation of any given point in the pipe line. From this
vertical measurement, which is usually stated in feet, is ob-
tained the internal pressure per square inch which is herein-
after described under the title of Pressure.
TOTAL HEAD.— The Total Head (sometimes called Total
Fall) is the difference in elevation between the water at the
intake and the surface of the water at the outlet and, in con-
nection with gravity lines with an open end discharge, is
the sum of three items, viz.: Friction Head, Velocity Head
and Entrance Head, which are defined in order.
FRICTION HEAD.— Assuming a gravity line discharging
into a reservoir with the discharge end under the surface of
the water, the Friction Head is the difference in elevation
between the surface of the water at the intake and the elevation
of the water at the outlet after the sum of the Velocity Head
and the Entrance Head shall have been deducted. Should the
discharge pipe be above the surface of the water then the
center of the discharge end should be considered rather than
the surface of the water in the reservoir.
Friction Head, also known as Loss due to Friction, is the
difference in pressure (resolved into feet head) between any
12 PACIFIC TANK & PIPE COMPANY
two given points in a continuous line of pipe, the difference in
pressure being due to the friction between the water and the
interior surface of the pipe.
From the Friction Head is obtained the slope governing
the flow of water in the pipe. This slope will be recognized
under a definition given later as the Hydraulic Gradient.
VELOCITY HEAD.— The Velocity Head is a distance
measured down from the surface of the water at the intake
and is determined by the law of falling bodies. In order that
the water in the pipe may flow with sufficient velocity to
maintain the discharge for which it is designed a certain dis-
tance, or fall through space, must be utilized by the law of
gravity in obtaining that velocity.
ENTRANCE HEAD.— The Entrance Head is generally
assumed to be half of the Velocity Head and is due to the
resistance caused by the eddies produced by the water entering
the end of the pipe. This may be to a great extent overcome
by using an enlarged or funnel shaped intake, but in most cases
the velocity is not sufficiently great to make this item of
moment. Especially is this true of long pipe lines where with
a comparatively low velocity both the Entrance Head and
the Velocity Head are so small that they can be omitted from
consideration.
PRESSURE HEAD. — The Pressure Head is the difference
in elevation between the surface of any confined body of water
and any point in the container where it may be desired to
ascertain the pressure. After the Pressure Head has been
determined the pressure in pounds per square inch is obtained
by multiplying the head in feet by .4335. The pressure in
pounds per square inch at any given point is equivalent to the
actual weight of a column of water one inch square and equal
in height to the Pressure Head.
PUMPING HEAD. — The Pumping Head is the sum of the
Static Head and the Friction Head necessary to discharge the
given quantity of water.
DYNAMIC HEAD.— The Dynamic Head, or Head or Fall
PACIFIC TANK & PIPE COMPANY 13
actually used in the production of power, is the difference in
elevation between the point of discharge and the hydraulic
gradient. In connection with turbine wheels the discharge
point may be assumed to be the elevation of the tail water
while in the case of tangential wheels the elevation of the center
of the wheel should be considered.
In the design of a pipe line for a power system a certain
amount of head is assumed to be lost, which is made up of the
sum of the Friction Head, the Entrance Head and the Velocity
Head. The remainder of the total head is the actual fall of
water after all deductions have been made for the frictional
and other losses and is the fall actually employed in producing
power.
WORKING HEAD.— Working Head is a term frequently
used and is generally misleading and therefore is not here
defined.
HYDRAULIC GRADIENT OR HYDRAULIC GRADE
LINE. — In the case of a pipe line having but one intake and
one point of discharge, the Hydraulic Gradient is a theoretical
line drawn from the surface of the water in the outlet to a point
in the intake. This point is determined by measuring down
from the surface of the water a distance corresponding to the
sum of the Entrance Head and the Velocity Head. On the
basis of the slope indicated by this line the velocity of the
water is calculated.
The Hydraulic Gradient will be a broken line:
1. — If there be any change in the diameter of the pipe.
2. — If water be drawn off at a point or points other than
the one point above mentioned.
3.— If any part of the pipe be constructed above a straight
line drawn between the ends of the pipe.
This definition does not cover the various phases of the
Hydraulic Gradient and for illustration we refer you to the
drawings on page 10 and for still further information to the
various engineering text books on the subject of Hydraulics.
14 PACIFIC TANK & PIPE COMPANY
SLOPE.— The Slope of the pipe line is obtained by dividing
the Friction Head by the length of the pipe line. This result,
in order to obtain the basis on which our table is calculated,
must then be multiplied by 1000.
COEFFICIENT OF FRICTION or COEFFICIENT OF
ROUGHNESS.— The term Coefficient of Friction as used in
formulae relating to the flow of water in pipes or channels is a
factor indicating the resistance due to friction caused by
roughness of the surface in contact with the flowing water.
Were the element of roughness entirely eliminated, the
water would fall, by its own weight, according to the natural
laws of gravity. The coefficients used in the Flow Tables
given in this book have been selected as representing as nearly
as possible the actual condition of friction encountered in
wooden pipes. It is well to bear in mind that after service of
a year or two, the interior of wooden pipe is much smoother
than when new, the amount of friction is correspondingly less
and as a consequence the velocity and discharge are greater.
On the contrary, the flow of water in metal pipe never is as
great as in wooden pipe and after short service the metal
pipe tuberculates and corrodes to such an extent as to greatly
increase the friction and diminish the discharge.
MEAN RADIUS OR HYDRAULIC RADIUS.— The Mean
(or Hydraulic) Radius is the quotient, in feet, obtained by
dividing the area of wet cross-section in square feet, by the
wet perimeter in feet. In pipes running full or exactly' half
full, and in semi-circular open channels running full, it is equal
to one-fourth of the inner diameter.
WET PERIMETER.— The Wet Perimeter is the sum of
the lengths, in feet, found by measuring across the channel,
such parts of its sides and bottom as are in contact with the
water.
EXAMPLE. — A channel 3 feet deep by 6 feet wide with
water running 2 feet 6 inches deep, has a Wet Perimeter equal
to 2 feet 6 inches plus 2 feet 6 inches plus 6 feetO inches = 11 feet.
The area of wet cross-section is 2J^x6 = 15 square feet.

HYDRAULIC DATA
Gallons per day (24 hours) multiplied by .000001547 equals
Cubic Feet per Second.
Cubic Feet per Second divided by .000001547 equals Gallons
per day (24 hours).
A Cubic Foot of Water contains nearly 7^ gallons (7.48052)
and weighs about 62J^ pounds.
A Gallon of Fresh Water weighs 8.34 pounds and contains
231 cubic inches.
27154 Gallons of Water (3630 Cubic Feet) will cover one
acre one inch deep.
The Miner's Inch has varying actual values in different
states as follows :j
One Second Foot equals 50 Miner's Inches in Utah, Idaho
and Nevada.
One Second Foot equals 40 Miner's Inches in Montana and
Arizona.
One Second Foot equals 38.4 Miner's Inches in Colorado.
Note. — The Miner's Inch given in the Flow Table in this
book, is that generally spoken of as the California Inch, or
1/50 of one second foot, which is customarily used by miners
in that State. The California statute, however, provides that
the Miner's Inch shall equal \Yi cubic feet per minute, or one
second foot equals 40 Miner's Inches.
One Acre Foot equals 43560 Cubic Feet = one second foot
of water flowing for 12 hours and 6 minutes.
Doubling the diameter of a pipe multiplies its end area four
times.
Theoretically water can be raised by suction 33 feet, but
practically only 25 to 28 feet.
The amount of power developed by water flowing through
a pipe may be ascertained by the following formula:
Horse Power = .1134HS
in which H equals the dynamic head in feet;
S equals the cubic feet of water per second.
This gives a strictly theoretical result and from it must be
deducted from 20% to 30% to cover machine inefficiency.
Example. — 50 second feet of water with 75 foot head:
75 times 50 times .1134=425. Deducting 20% for inefficiency
will give 340 Horse Power.

Example Showing the Application of the above Table.
Suppose the Weir to be 60 inches long, and the depth of water
on it to be 5^ inches. Follow down the left-hand column of
the figures in the table until you come to 5 inches. Then run
across the table on a line with the 5, until under H on top line,
and you will find 5.15. This multiplied by 60, the length of
Weir, gives 309, the number of cubic feet of water passing per
minute, and[this multiplied by 7H will give the gallons — 2317^.

RULE.— Find the Mean Radius of the channel or flume by the method
described under definitions of Mean Radius and Wet Perimeter.
Take from the table of velocities the number opposite the Mean Radius and
under the suitable coefficient of roughness. This number must 1 e multiplied
by the multiple opposite the fall in the table of slopes. The result is the velocity
in feet per second.
The quantity of water discharged is found by multiplying the area of the
wet cross-section by the velocity.
EXAMPLE
A box flume has four foot straight sides and an inside width of five feet,
the water being calculated to run 3.75 feet deep with a fall of 1H inches per
100 feet.
The wet perimeter is found to be 3.75 plus 3.75 plus 5 = 12.5 feet.
The area of the wet cross-section is 3.75 x 5 = 18.75 square feet.
The Mean Radius is therefor 18.75 ~ 12.5 = 1.5.
Assuming that the coefficient in this case is .015. we refer to the table of
velocities and under .015 and opposite 1.5 we find 13.11. Now refer to the table
of slopes and opposite l}-g" we find the multiple .346. Multiplying 13.11 by .346
we obtain 4.54, which equals the velocity in feet per second of the water in the
flume. The quantity of water carried by the flume is found to be 18.75 x 4.54 =
85.1 cubic feet per second.

TABLES FOR FLOW OF WATER THROUGH
WOOD PIPE
In preparing the following tables for the flow of water
through wooden pipes, such as are manufactured by us, we
have given full consideration to all of the few tests that have
been made from which intelligent deductions can be drawn.
Unfortunately, most of the tests that have been made were
with pipe constructed under unusual conditions or with greatly
varying grades or curvature. It is our intention to show in
these tables as nearly as possible the actual amount of water
that will flow through wooden pipes with a minimum amount
of curvature either vertical or horizontal. Should there be,
in a long line of pipe, merely three or four curves of considerable
radius, the flow would not be affected to any appreciable extent.
In preparing these tables we have used the "Kutter"
formula and a changeable value of "n." The diagram on the
opposite page shows the various values of "n" for all pipes
from 2 inches up to 168 inches in diameter. It will be observed
that the coefficient 0.011 is used for the larger diameters and
that this valuation is slightly decreased for the smaller diam-
eters. Many engineers calculate the flow of water in wood
pipe with the valuation of "n" = 0.010. We believe that the
valuation which we have given is safe and for reasonably
straight pipes can be used without hesitancy.
We present a few examples of the use of this table which
will readily explain how the size of pipe can be ascertained to
deliver certain quantities of water, or how with the size given
the frictional loss can be determined; in fact, the intelligent
use of these tables can be made to do away entirely with the
long tiresome calculations that are beyond the reach of the
layman and are a tedious and complicated piece of work for
the practicing engineer.
You will note that the first column represents the loss of
head due to friction in 1,000 feet of pipe when discharging a
given quantity of water. This frictional head can be applied
to any length of pipe by multiplying by the number of thousand
feet and fraction thereof, the result being the total frictional
208776
38 PACIFIC TANK & PIPE COMPANY
loss in the entire pipe. The second column shows the mean
velocity in feet per second, an item which is rarely considered
by the layman. The third column is the discharge of the pipe
in cubic feet per second. The fourth gives the discharge in
gallons per minute and the fifth gives the discharge in miner's
inches. The miner's inch used herein is equivalent to one-
fiftieth of a cubic foot per second.
In the last column is given the combined entrance and ve-
locity heads. This figure represents the head of water which
should stand over the top of the pipe at the intake in order to
give the body of water in the pipe the velocity, and conse-
quently, the discharge required. This item can be reduced
nearly one-third provided that the intake end of the pipe is
enlarged so as to eliminate the entrance friction. (See definition
of Entrance Head.)
EXAMPLES
1. Pipe to be used as an Inverted Syphon.
[Size of pipe 60 inches.
Given] Length of pipe. . .3200 feet.
[Discharge 286 cubic feet per second.
Required— Total Head.
Turning to the table showing a diameter of 60* we find
opposite the discharge of 286 cubic feet per second, that 8 feet
of head is required for friction in each 1000 feet of pipe. The
friction in the entire line is therefore found by 3.2x8 = 25.6
feet. Glancing across the same line from which we obtained
the friction head, we find that 4.9 feet is required for velocity
and entrance head. This added to 25.6 equals 30.5 feet, which
is the Total Head required to discharge the given quantity of
water.
Should occasion occur in which the exact discharge required
is not found in the table, the friction head as well as the velocity
and entrance heads can be determined, sufficiently close, by
comparison with adjoining discharges and heads either by the
eye or by simple proportion.
Should the quantity of water given be stated in gallons per
minute or in miner's inches, the calculation would be effected
in the same manner.

2. Pipe to be used as an Inverted Syphon.
(Length of pipe 4800 feet.
Given] Discharge 92 sec. feet.
[Total Head 36.2 feet.
Required — Size.
As part of this Total Head will be taken up as velocity and
entrance head, until we know the exact velocity, we can obtain
only an approximate result. We therefore proceed to divide
the Total Head by the number of thousands of feet of length:
36.2 divided by 4.8 equals 7.5 plus. Now let us assume that
the .5 feet will be devoted to velocity and entrance head and
the 7 feet to the friction head in 1000 feet of pipe. Referring
to the table, and after examining several pages we find that
under a diameter of 40 inches and opposite 7 feet is the required
discharge, namely 92 sec. feet. We now multiply for the exact
friction head: 7x4.8 equals 33.6 feet. To this add 2.6 for
velocity and entrance head, giving a total of 36.2 feet. 40
inches is therefore the diameter required. In this example, it
is sometimes necessary to make several trials before the
correct result is obtained.
3. Pipe to be used as an Inverted Syphon.
f Size 20 inches.
Given] Length 4260 feet.
[Total Head 22.16 feet.
Required — Discharge.
Divide 22.16 by 4.26 equals 5 plus. Assuming the friction
head to be 5 feet, the total friction head will be 5 multiplied
by 4.26 equals 21.30. To this add velocity and entrance head
.86 feet equals a total head of 22.16 feet. From the table op-
posite a friction head of 5 feet per 1000 it is found that the
discharge is 13.3 sec. feet, the answer sought.
4. A pipe supplying water for a Power Plant.
The'size of pipe, the discharge and the friction, velocity and
entrance heads may be determined as shown above but it
must not be forgotten that the dynamic head is the important
factor to be considered. From this alone power is developed.
An increase in pipe diameter means less friction head and more
dynamic head and consequently an increase in the number of
horse power developed.
40 PACIFIC TANK & PIPE COMPANY
The economic size of pipe to employ should be given the care-
ful study of a capable engineer.
5. A pipe used as a Pumping Line.
In pumping from a source of supply to a reservoir or ditch
the water may be assumed to be lifted straight up in the air
to such a height that it will, by gravity, flow to the point of
discharge. For example, a pump is required to lift 3000 gallons
per minute through 3500 feet of 16* pipe to a reservoir having
its water surface 43 feet above the pump. Referring to the
table, it is found that in discharging 3000 gallons per minute
through a 16" pipe, there is 4 feet of friction head per 1000
feet of pipe, or 4 multiplied by 3.5 equals 14 feet in the entire
line. The pump will therefore be compelled to work against
a pumping head of 43 feet plus 14 feet equals 57 feet.
The diameter of pipe selected is governed largely by the
cost of pumping and the experienced engineer should be called
upon for an economic consideration of the subject.
