Question

CHE 3333 Introduction to Transport Phenomena Fall 2023 Problem 1. (3 pts) A viscous film drains uniformly down the side of a vertical rod of radius R. You may assume that

the flow is fully developed and that the liquid forms a film with a constant thickness of h. You may also neglect the shear resistance due to the atmosphere. Use the shell balance approach to determine the velocity distribution in the film.
