There is fluid film with thickness of h between two flat plates. The upper plate moves to the right at speed of U. The lower plate is stationary.

a. Find the velocity profile for flow between flat plates. Use Navier-Stokes equations. Provide a detailed solution. Specify all simplifying assumptions that you make, and clarify how each assumption simplifies the problem.
b. Draw the velocity profile for dp/dx = -5 Pa/m
c. Draw the velocity profile for dp/dx = +5 Pa/m

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
