MCQ : Compressible flow
Nitrogen is escaping from a pressurized bottle (internaltemperature 300 K, internal pressure 650 kPa) through an open valvethat happens to be shaped like a converging-diverging nozzle, withan area ratio of 10 on the diverging side of the throat. What arearatio at the shock is required to get the exit pressure from thenozzle to equal atmospheric pressure (100 kPa)? (It’s a fairlycomplex calculation, so your answer may differ by 1 or 2 in theleast significant figure shown.) a)1.53 b)8.32 c)8.67 d)9.62
