Problem 3. A particular laminar boundary layer velocity profile is given by the following equation, where y ≤ 8 and at y = 8, u = U. (Ue is the freestream

velocity away from the surface): u(y) 2 UC ² = ² ( 5 ) - ( 1 ) ² Ue (a) Find the shear stress (t) as a function of the distance from the wall (y) and the shear stress at the wall surface.
