Chap.1 1.7-1.10 Problem 1.34 6 of 12 The Newtonian fluid shown in is confined between the plate and a fixed surface as shown in . Its velocity profile is defined by u = (8y-0.3y2) mm/s, where y is in mm. The plate has a surface area of 31(103) mm2 in contact with the fluid. Take μ = 0.482 N·s/m2. Suppose that h = 8 mm. Part A Determine the force P that must be applied to the plate to cause this motion. Express your answer to three significant figures and include the appropriate units.
