A fluid with viscosity 0.04 lb/ft$^2$ flows between two stationary plates as shown below, and the velocity distribution of the fluid follows the relation:
$V_x = \frac{3\bar{V}}{2} \left[ 1 - \left( \frac{y}{h} \right)^2 \right]$
Assuming that the average velocity of the fluid is 2 ft/s and the distance between the two plates is 0.4 inches, the goal is to calculate the shear stress on the bottom plate as well as at the centerline.
