Atop plate is moving over a second fixed plate to the right with a constant velocity of u=3 ms. the gap between the two plates is h=6mm and is filled with a fluid of dynamic viscosity p. ssx.10 pas. a 1) assuming linear velocity distribution, calculate the shear stress on the upper and bottom plates. 2) assume a nonlinear velocity of the form v 6.99+0.873 in y where y is the distance from the bottom fixed plate. calculate the shear stress for y 3 mm.
