I say that if each layer is supposed to tend to move with an infinitely small velocity
+ dw, the fluid will remain in equilibrium. “For since v = v T. du + dw, and the
velocity of each slice is supposed not to change in direction, each layer can be ...
Therefore, if it is supposed that s dys ds V(po-FT) = R, in its totality, then k = 4R —
M. “In the following instants parts of the fluid evidently retain the velocities uq and
up, from which it is easy to see, by means of our theory on the resistance, that ...
We must then conclude that p'(f) is inappreciable, and can be supposed to be
zero, on the Earth. “If the equation p'(f)=0 was obtained whatever the force f might
be, p(f) would be constant and the velocity would be proportional to the force.
