PIU 15 a 2.8) Olive oil (u = 3 X 10-4 slug/ftos, v = 1.8 x 10-4 ft2/s) flows over a wooden plank with a velocity profile given by u = 53y - 1215y2 ft/s where y is the distance from the plank in feet. What is the shear stress at the surface of the plank, and where is it a maxi- mum? fin mn chowe air at 150 flows
