1. An oil is flowing between two parallel horizontal plates which are 20mm apart. The top plate is moving with a uniform speed 0.1m/s. The viscosity of the oil is 0.1N.s/m2. The velocity at the centerline is 1.95m/s. Consider the flow to be a fully developed one. a) Derive the velocity profile b) Calculate pressure difference between two points (P1P2)5m apart c) Find the velocity at 3mm from the wall of the bottom plates. d) Find the velocity at 3mm from the wall of the top plates
