The velocity distribution for flow over a plate is given by u = 0.5 y - y2 where u is the velocity in m/s at a distance y metre above the plate. If the dynamic viscosity of the fluid is 0.9 N/m2, then what is the shear stress at 0.20 m from the boundary?-A-0.9 N/m2B-1.8 N/m2C-2.25 N/m2D-0.09 N/m2-D-0.09 N/m2

D 0.09 N/m2 Given: u = 0.5y y^2. du/dy = 0.5 2y. Shear stress = dynamic viscosity x du/dy. = 0.9 x (0.5 2y), = 0.9 x (0.5 2x0.20), = 0.9 x (0.5 0.4), = 0.9 x (0.1), = 0.09 N/m^2.0
