Air at T = 25 C° and p = l atm flows past a long flat plate, at the end of which is placed a narrow scoop, as shown in the figure below. (a) Determine if the boundary layer is laminar or turbulent at the position of the scoop assuming Rex,trans=5*10 (b) estimate the height h of the scoop if it is to extract 4 kg/s per meter of width b into the paper. (c) Find the drag on the plate per meter of width, D/b up to the inlet of the scoop.
