Make assumptions and show all your work. 1. A viscous liquid is supplied from a vertical capillary tube to a solid cylinder of radius R, and the resulting film of liquid flows radially across the top of cylinder to the outer edge. Beyond the edge, the liquid flows down the outside of the cylinder under gravity. (a) (25%) If the film thickness, 8, along the outside of the cylinder is constant, derive an expression for the velocity profile uz(r) for the film flow in the region along the side of the cylinder. State all the assumptions you use. 2r So Slider
