please ist assumptions, show work, and
explain your reasoning carefully! please dont forget all this
thanks
2. A vertical moving belt drags an incompressible liquid film of thickness h, density P, and viscosity H, as shown. Gravity tends to make the liquid drain down, but the movement of the belt at speed U, keeps the liquid from running off completely. Assume...

Consider the steady, incompressible flow of depth h of a liquid
of known density ρ and unknown viscosity µ down a flat plate as
shown in Figure 1. Air is the fluid above the liquid layer. The
force of gravity is in the vertical direction with acceleration g,
and the plate is at an angle θ with respect to the horizontal.
Assuming the coordinate system as shown, with x aligned with the
flow direction, and y normal to the plate,...

An important problem in chemical engineering separation equipment involves thin liquid films flowing down vertical walls due to gravity, as shown in this figure yV A. Assume that the wall is long and wide compared to the film thickness, with steady flow that is laminar and fully developed: u= v=0 and w w(x). Using a force balance on a rectangular differential element, derive an expression relating g, p, and τΧΖ . Use τΧΖ-n(-_ +--) for a Newtonian fluid to convert...

4. An incompressible fluid with viscosity u and density p was contained in pipe of length L and radius R. Initially the fluid is in rest. At t=0, a pressure difference of AP is applied across the pipe length which induces the fluid flow in axial direction (V2) Only varies with time (t) and pipe radius (r). There is no effect of gravity. To describe the fluid flow characteristics, after the pressure gradient is applied, answer the following questions: a)...

12. A liquid flows in a slit in the z-direction down a vertical plane, between 2 broad parallel plates with distance L under the influence of gravity,g, with the plane parallel to the axis of gravity. Assume a uniform thickness of 2D for the liquid layer in the x-direction, steady state laminar flow, and that the fluid is Newtonian and incompressible. The plate at x=0 is heated to a constant temperature of Tp and all the fluid enters the slit...

An incompressible fluid flows between two porous, parallel flat plates as shown in the Figure below. An identical fluid is injected at a constant speed V through the bottom plate and simultaneously extracted from the upper plate at the same velocity. There is no gravity force in x and y directions (g-g,-0). Assume the flow to be steady, fully-developed, 2D, and the pressure gradient in the x direction to be a constant P = constant). (a) Write the continuity equation...

Two horizontal plates with infinite length and width are separated by a distance H in the zdirection. The bottom plate is moving at a velocity vx=U. The incompressible fluid trapped between the plates is moving in the positive x-direction with the bottom plate. Align gravity with positive z. Assume that the flow is fully-developed and laminar. If the systems operates at steady state and the pressure gradient in x-direction can be ignored, do the following: 1. Sketch your system. 2....
