Question

A flat plate is oriented at an angle of attack of 90⁰ to the flow in a low-speed wind tunnel. Assume the pressure over the front of the plate is constant and equal to the stagnation pressure. Assume the pressure on the reward facing side is also constant but equal to the free stream static pressure. Since the flat plate is perpendicular to the flow, the resulting drag is primarily pressure drag as opposed to skin friction drag. Show that the drag coefficient for this flow is C_D = 1.

Answer 1

please like thank you.... and in your question, it should be instead of 900...
