Normal shock wave
1. Consider a NSW with a downstream-upstream temperature ratio of 3.5 what is the mach number upstream and downstream of the shock? Show your solution.
2. The flow just upstream of a NSW is at SSLC and the mach number downstream is 0.6152 determine the pressure, temperature, density, velocity, and the total pressure and temperature. Show your solution
3. The mach number behind of a NSW is 0.4752
What is the mach number in front of the wave and the pressure ratio across the shock? Show your solution.
