5) A continuous belt passes upward at an angle with the horizontal through a chemical bath at a velocity v0 and picks up a film of liquid of thickness h, density , and viscosity . Gravity tends to make the liquid drain down, but the movement of the belt keeps the fluid from running off completely. Assume well-developed laminar flow with no pressure gradient, and the atmosphere produces no shear at the outer surface of the liquid. Use a Cartesian coordinate system for the problem with the belt movement in the positive x-direction and the film thickness in the y-direction. a) Clearly state the boundary conditions at y=0 and y=h to be satisfied by the velocity profile. b) Obtain an equation for the velocity profile. c) Assume the belt has a width W. Determine the volumetric flow rate at which the fluid is being dragged up with the belt in terms of ,,v0,h,W
