A steady laminar boundary layer is formed over a flat plate as shown in the figure. The free stream velocity of the fluid is Uo. The velocity profile at the inlet a-b is uniform, while that at a downstream location c-d is given by u = Uo[2(y/δ) - (y/δ)2].
The ratio of the mass flow rate, ṁbd, leaving through the horizontal section b-d to that entering through the vertical section a-b is ________.
Correct : 0.33
