PART B — (5 * 16 = 80 marks)
11. A viscous fluid is in laminar flow in a parallel plates, a distance 2B apart. The length and width of the plates are L and W respectively. Obtain the expressions for the distribution of velocity, maximum velocity, average velocity and volumetric flow rate. Assume that the liquid is flowing from top to bottom.
