Consider flow of a thin, uniform film of an incompressible Newtonian liquid on an infinite, inclined plate that moves upwards with constant speed V, as shown in Fig. The ambient air is assumed to be stationary, and the surface tension is negligible. (a) By using sell momentum balance calculate the velocity ux(y) of the film in terms of V, , , , g and . (b) Calculate the speed V of the plate at which the net volumetric flow rate
