Problem 3. A particular laminar boundary layer velocity profile is given by the following equation, where y 8 and at y = 8, u = Ue (Ue is the freestream velocity away from the surface): 2 )-() u(y) = 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.
