Consider the supersonic flow over a 5° half-angle wedge at zero angle of attack, as sketched in Figure 1.16a. The freestream Mach number ahead of the wedge is 2.0, and the freestream pressure and density are 1.01 × 10$ N/m² and 1.23 kg/m', respectively (this corresponds to standard sea level conditions). The pressures on the upper and lower surfaces of the wedge are constant with distance s and equal to each other, namely, pu = pi = 1.31 × 10° N/m², as shown in Figure 1.16b. The pressure exerted on the base of the wedge is equal to pœ. As seen in Figure 1.16c, the shear stress varies over both the upper and lower surfaces as r, = 431s-0.2. The chord length, c, of the wedge is 2 m. Calculate the drag coefficient for the wedge. 34.2 Wae ange
