The velocity distribution for the flow of crude oil at 100F ( = 8 105 lbfs/ft

The velocity distribution for the flow of crude oil at 100°F (μ = 8 × 10–5 lbf∙s/ft²) between two walls is shown and is given by u = 100y(0.1 – y) ft/s, where y is measured in feet and the space between the walls is B = 0.1 ft . Plot the velocity distribution and determine the shear stress at the walls.
