UNIVERSITY OF ARIZONA DEPARTMENT OF CHEMICAL AND ENVIRONMENTAL ENGINEERING CHEE 305 TRANSPORT PHENOMENA SPRING 2017 Problem Set 2 Due: Friday, February 3 1 . A large solid block (see figure) slides down a slope on the surface of a liquid (density and viscosity ) at a constant velocity v 0 . Because upstream and downstream from the block the liquid film is exposed to the atmosphere, you may assume that pressure in the liquid between the block and the solid surface does not change with x. You also may assume that the liquid film has a uniform thickness . (a) Find an expression for the velocity profile v x (y) in the liquid contained between the block and the solid surface. Assume that the flow is steady and incompressible. Sketch the profile. (b) If the surface area of the block that is in contact with the liquid is A 0 , find the force that the liquid exerts on the block in the x direction in terms of v 0 . (c) If the mass of the block is M, find an expression that can be used to calculate v 0 .

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
