Question

Consider the laminar flow between two parallel plates (separation: a) where the
upper plate moves with a constant velocity U, while the bottom one is stationary. The
flow is generated due to the combined effect of an applied pressure gradient and the
upper moving plate.
The velocity profile is shown in the image. 

(a) Find the shear stress of the equation shown in the image. 
(b)  Find the volumetric flow rate if the width of both plates is W.
(c)  Find the average velocity.
(d)  Find the maximum velocity. At which location is the velocity maximum?
