FINAL EXAM ENGR 33: Nieh CUA 16 Summer PART 11. 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.

Solution

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