A Newtonian fluid descends through parallel plates oriented

vertically. The plates are separated by a distance L on the x axis.

Determine:

a) The equation to be solved to know the velocity of the fluid.

b) The velocity profile of the fluid.

c) The volumetric flow through the plates.

d) Consider that an experiment is carried out in which the fluid is made to flow at 5C

and another in which the fluid flows at 30C, when will it flow faster and why?

e) If two immiscible fluids flow in this system, make a diagram, define

the boundary conditions that would be needed to solve the problem and

Comment in detail how it would be resolved.
