Problem 2. When a sea-level airflow approaches a ramp of angle 20, an oblique shock wave forms as depicted in figure 1. Calculate (i) Ma, (ii) p2, (iii) T and (iv) V2. The air temperature, pressure and density are 288.16 K, 101.325 kPa and 1.2255 kg/m, respectively. State 2 State 1 40 deg. 20 deg. Figure 1: Compressible flow over a ramp. Problem 2.
