Question: the air temperature is 288k and the pressure is 1...

Question details

The air temperature is 288K and the pressure is 1 atm upstream of a shock wave; After the passing through the shock wave, the temperature of the air is 690K and the pressure is 8.656 atm. Calculate the change in a) enthalpy b) internal energy, and c) entropy across the wave. Assume R = 0.287 kJ/kg⋅K and 𝛾 = 1.4
