Students conducted an experiment to evaluate the velocity profile,u(y), of a fluid flowing over a flat plate (Figure-3). Different students have reported different variations of velocity with vertical distance y from the plate as below.  u(y)=y^2−2aby   Obtain a relation of shear stress and wall shear stress in terms of a and b using the appropriate velocity profile. Calculate the shear stress at location y = 0.005 m, if the viscosity of the fluid is 60 Pa-s.
