Air is flowing along a flat plate. Air velocity is 1 m/s. Calculate 1 m from the leading edge of the plate, a) the thickness of the velocity boundary layer b) the thickness of the thermal BL. c) velocity 2 cm from the plate (1 m from the leading edge). d) Now assume that fluid is water. Calculate the thickness of the thermal BL at the point where thickness of the velocity boundary layer is 5 mm.
