336 HYDRODYNAMICAL PROBLEMS SUGGESTED BY PITOT'S TUBES
When -v/r differs from zero, the calculations are naturally more com]: The most interesting and instructive cases occur when ty is small, chosen o|r = 1/10; The corresponding values of £, x, and y are g: Table III, calculated from equations (10), (11), and a plot is shown in
As in the former problem, where the liquid is supposed to adhere walls notwithstanding the sharp edges, the pressure in the recesses tube is simply that due to the velocity at a distance. At othei the pressure can be deduced from the stream-function in the usual WE008 0-60 3-1089 0-162
