Rework Problem 4.14 if the plates are circular and have radius L.

Data From Problem 4.14

Two very long parallel plates of length 2L are separated a distance b. The upper plate moves downward at a constant rate V. A fluid fills the space between the plates. Fluid is squeezed out between the plates. Determine the mass flow rate and maximum velocity under the following conditions:

a. The exit velocity is uniform.
b. The exit velocity is parabolic.
