18. A thin 30 cm x 30 cm flat plate is pulled at 3 m/s horizontally through a 3.6 mm thick oil layer between two plates, one stationary and the other moving at a constant velocity of 0.3 m/s as shown. The dynamic viscosity of the oil is 0.027PA-s. Assuming the velocity in each oil layer to vary linearly. (a) Plot the velocity profile and find the location where the oil velocity is zero and (b) determine the force that needs to be applied on the plate to maintain this motion.. Fixed wall h =I mm V= 3 m/s F h232.6 mm V- 0.3 m/s Moving wall
