Unformatted text preview: b) Calculate the thickness of the turbulent boundary layer at a point 1.0m from the leading edge. 3. Let us represent a rectangular wing of an airplane by a flat plate. The dimensions of the wing are chord=4 ft and span=28 ft and the motion is at standard sea level conditions. a) If the airplane is moving down the runway at 10 mph, what is the drag coefficient (due to skin friction) for the wing? b) If the airplane is moving down the runway at 10 mph, what is the total skin friction drag (in Newtons) acting on the wing? c) If the airplane is flying at 170 mph, what is the drag coefficient (due to skin friction) for the wing?...
