One dimension of a rectangular flat plate is twice the other. Air at uniform speed flows parallel

Question:

One dimension of a rectangular flat plate is twice the other. Air at uniform speed flows parallel to the plate, and a laminar boundary layer forms on both sides of the plate. Which orientation—long dimension parallel to the wind (Fig. P10–102a) or short dimension parallel to the wind (Fig. P10–102b)—has the higher drag? Explain.
