3. A crude approximation for the x component of velocity in an incompressible laminar boundary layer is a linear variation from u=0 at the surface (y=0) to the freestream velocity, U, at the boundary-layer edge (y=). The equation for the profile is u=Uy/, where =cx1/2 and c is a constant. Show that the simplest expression for the y component of velocity is v=uy/4x. Evaluate the maximum value of the ratio v/U, at a location where x=0.5m and =5mm
