A steady normal shock wave occurs in an air flow at a point where the velocity is 680 m/s, the static pressure is 100 kpa, and the static temperature is 50°c. calculate the velocity, and static press

A steady normal shock wave occurs in an air flow at a point where the velocity is 680 m/s, the static pressure is 100 kpa, and the static temperature is 50°c. calculate the velocity, and static pressure and temperature downstream of the shock. also calculate the stagnation pressure and temperature upstream and downstream of the shock (as measured in the reference frame where the velocity measurement was 680 m/s).
