FLUIDITY AND PLASTICITY

lower than at a fluidity of 200. This is as one would expect.
From these values of the association the temperature coefficient
of the association factor can be obtained. (Bingham (1910),
page 306.)

From the constants at different fluidities one may conceivably
obtain a series of points on the fluidity-temperature curve
heretofore unknown perhaps, and using these points the whole
curve may evidently be drawn.

The constants for fluidities 200 and 300 are for convenience
grouped together in Table XXXIII.
