12. Consider steady, incompressible, parallel, laminar flow of a film of oil falling slowly down an infinite vertical wall as shown in the figure(Fig. P12a). The oil film thickness is h, and gravity acts in the negative z-direction (downward in the figure) There is no applied (forced) pressure driving the flow the oil falls by gravity alone. (1) Calculate the velocity field in the oi film and sketch the normalized velocity profile. And generate an expression for the volumetric flow...

Consider the steady, laminar flow of two liquids, A and B, with viscosities HA-μ and μΒ 21, respectively, between infinite parallel plates at 2- a, as shown in the diagram below. The plate at 2 a is fixed, while the plate at 2a moves with constant velocity -Vi, where V0. The liquids do not mix, and each forms a layer of depth a. There is an applied pressure gradient acting on both liquids, given by ▽p--Ci (where C > 0...
