The sketch shows a supersonic flow past a concave 10o corner. The flow before the turn is uniform and parallel and the velocity and density are 694 m/s and 1 kg/m3. The turn is accomplished through an oblique shock wave that makes an angle of 39.3 with the upstream flow direction. The shock is very thin. Flow after the shock is also uniform and parallel with velocity and density of 616 m/s and 1.46 kg/m3
