Question: 1. Two infinite plates are separated 0.01 in. by a liquid with a viscosity of 1.1 centipise (cP). The top plate moves at a velocity of 0.3 ft/s. The bottom plate is stationary. If the velocity decreases linearly from the top plate through the fluid to the bottom plate, what is the shear stress on each plate?
2. Two infinite plates are separated 0.2 mm by a liquid with viscosity of 0.9 cP. The top plate moves at a velocity of 0.1 m/s; the bottom plate is stationary. Assume velocity decreases linearly through the fluid to 0 at the bottom plate. What is the shear stress on each plate?
