We are measuring the drag force on a cylinder in a rectangular wind tunnel of width, W . We use air with a density, . The pressure is uniform at section A and B, but pA is different from pB. The air speed at section S is uniform (VA). At section B, the speed is described by the profile in the diagram. What is the force exerted by the flow on the object as a function of , H, W , VA, pA, and pB
