OPEN-BOOK TEST (45%, ~60 minutes), All Reference Allowed NAME: 11, (15%) Exact Solution -viscous Plow over Flat plate SCORE A wide flat convey belt passes vertically through a tank of viscous liquid at constant steady laminar velocity of V 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.

Explanation / Answer

external flow drags the diamater in to the air with 0.4 m
