A wide flat convey belt passes vertically through a tank of

A wide flat convey belt passes vertically through a tank of viscous liquid at constant steady laminar velocity of V_0 = 0.2 m/s as shown. The viscous force results in a liquid layer of thickness h = 0.01 m moving up with the belt, while the gravity pulls it down. Determine the velocity distribution and the average velocity in the liquid layer.
