Suppose you buy a 3 x 7-ft sheet of plywood and put it on your roof rack. You drive home at 45 mi/h. Part A - If the board is perfectly aligned with the airflow, how thick is the boundary layer at the end of the board? Part B - Estimate the drag on the sheet of plywood if the boundary layer remains laminar? Part C - Estimate the drag on the sheet of plywood if the boundary layer is turbulent (assume the wood is smooth) and compare the result to that of the laminar boundary layer case. HINT - 3 X 7-ft sheet of plywood and put it on your roof rack. You drive home at 45 mi/h.
