Consider the flow of air over a small flat plate that is 15 cm long in the flow direction and 1 m wide. The free-stream conditions correspond to standard sea level, and the flow-velocity is 50 m/s. a) Assuming laminar flow, calculate the drag force on the plate. b) What would be the answer if the flow was assumed turbulent over the entire flat plate? c) If the length of the plate is doubled while the freestream velocity is kept constant, what will be the resulting drag? Compare the results to a) and b) and justify your answer.
