5.23 There is a fully developed laminar flow of an incompressible fluid between two infinite parallel plates separated by a distance 2 h as shown in the figure. The top plate moves with a velocity V0 and there is a negative pressure gradient dp dx

(pressure decreases in the x-direction). Derive an expression for the velocity profile. Determine the pressure gradient and the rate of rotation for which the flow rate is zero.
