2.27. Velocity profiles are measured at the upstream end (surface) and at the downstream end (surface 2) of a rectangular control volume, as shown in Fig: P2.27. If the flow is incompressible, two-dimensional, and steady, what is the drag coefficient for the airfoil? The vertical dimension H is 0.025c and
