A square flat plate with sides of length L = 2m and a negligible thickness (out of the page) is held stationary in a stream of air that is moving steadily at standard conditions past the plate with a speed U = 10 m/s that is uniform except for the boundary layers. Assume the plate is oriented so that only friction drag is important. Determine the drag coefficient for this plate.
