Fluid Mechanics - Viscous Fluid Contained Between Two Infinite Horizontal Parallel Plates Spaced 0.5

Problem/Example Statement: Viscous Fluid is contained between two parallel, horizontal, infinite plates that are spaced 0.5 inches apart. The bottom plate is fixed and the upper plate moves with a constant velocity, “U”. The fluid motion is caused by the movement of the upper plate. There is no pressure gradient in the direction of the flow. The flow is laminar. What is the required horizontal force per square foot on the upper plate to maintain its current velocity 2 ft/s? What is the pressure differential in the fluid between the top and bottom plate? Velocity of upper plate is 2 ft/s. Fluid viscosity is 0.03 lb s/ft^2. Specific weight 70 lb/ft^3. Coutte Flow Example
