Unformatted text preview: 1. (Viscous stress -— 25 pts) A thin plate of large area is placed midway in a small gap of height, h, filled with oil having a viscosity #0. If the plate is pulled with a force, F, a constant velocity, V, results. Now a lighter oil of viscosity ,Lt, is placed in the gap and it is found that the same force, F, will pull the plate at the same velocity, V, ifthe plate is unsymmetrically placed in the gap but still parallel to the walls. Assume a linear velocity distribution in the fluid. Find the viscosity ,u, in terms of ,u,J , h and the distance to the nearer wall, a.

    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.
