Aperfect gas expands in a frictionless nozzle. given that the expansion is isentropic, determine the following conditions at the final pressure: 1) velocity, 2) mach number, 3) temperature and 4) area per unit mass flow. how does the final flow area compare with the throat area for a given mass flow? the specific heat ratio is 1.4 and the molecular weight is 30 a. conduct this analysis for stagnation conditions po = 4 mpa, to-2500 k to ambient pressure 0.1 mpa. b. conduct this analysis for stagnation conditions po = 2 mpa, to-2500 k to ambient pressure 0.1 mpa. c. conduct this analysis for stagnation conditions po = 4 mpa. to - 3500 k to ambient pressure 0.1 mpa.
