A thin 15x10 cm plate is pulled at 2.2 m/s horizontally on a 3 mm thick oil layer with a stationary plate below. The dynamic viscosity of the oil is 0.025 Pa*s. a. Sketch the velocity profile and calculate the force needed to maintain this motion. b. If the thickness of the oil is cut in half but the force applied to the top plate remains the same, explain if the velocity of the top plate changes and why?
