3. Consider an incompressible laminar boundary layer that develops on a flat plate aligned with the freestream flow direction of speed U. The pressure is constant in the flow direction, i.e. Op/dx = 0. The vertical velocity component is constant and equal to -vw. U uly=0 =-vwj a) Determine the horizontal velocity component u(x, y). b) Is there any restriction on the value for Vw ? L 8
