= ²y - y²; where, y is 5) Velocity profile of a moving fluid over a flat (fixed) plate is given as: u = the distance from the fixed plate (y = 0) in m, u is the velocity in x direction in m/s. Calculate the shear stress on the fluid at y = 0.15 m if the viscosity of the fluid 8.6 poise (1 Poise- 1 dnes) cm²
