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.

Solution

there are direct formulas please find them in text book. i don\'t no how to how a formula should retuurn here
