2.28. Velocity profiles are measured at the upstream end (surface 1) and at the downstream end (surface 2) of the control volume shown in Fig. P2.28. Surfaces 3 and 4 are streamlines. If the flow is incompressible, two dimensional, and steady, what is the drag coefficient for the airfoil? The vertical dimension Hp is 0.025c. You will need to calculate the vertical dimen- sion of the upstream station (Hv). The pressure is p (a constant) over the entire surface of the control volume. (This problem is an extension of Problem 2.11.) Streamline ul HD 0.025c 2 4 Streamline Figure P2.28
