A uniform supersonic airflow traveling at passes over
a wedge (as Figure). An oblique shock, making an angle of 40° with
the flow direction, is attached to the wedge under these flow
conditions. If the static pressure and temperature in the uniform
flow are 20k Pa, -10 °C, respectively. Determine the static
pressure and temperature behind the wave, the Mach number of the
flow passing over the wedge, and the wedge half-angle.
