a 2. A solid plate slides down an inclined plane at a known constant velocity vo. The plate is suspended on a uniform liquid film of thickness 8 (see figure). The downward motion of the liquid is due to gravitational forces and the motion of the plate; that is, there is no pressure variation in the direction of motion (x). The liquid density and viscosity are p and u, respectively. Note that, since the control volume used in the analysis of flow down a slope (page 1-12) is independent of the boundaries, the momentum balance given by equation (1.34) still applies to this case.
