8.) Compute a theoretical drag coefficient, CD, for flow about a cylinder, neglecting friction drag. Find the pressure drag, assuming the following model for PCO):P=PO) on the front side of the cylinder is given by the potential flow result on the front side (see eqn. 6.109, 6.110; Fig. 6.25). On the rear side, there is a separated wake and the pressure is a constant equal to the potential flow value at 0 = 7/2, i.e. P= P(0 = 1/2) on the back side. Evaluate the drag force F per unit length using Eqn. 6.110 and a drag coefficient Cp = note A = D(1). Compare your result, which is independent of Re, with figure 9.15. F 0.5pv2D V V P=P(1/2)
