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.
