A perfect gas expands in a frictionless nozzle from stagnation conditions p 0 = 4 MPa, T0 = 2500 K to ambient pressure 0.1 MPa. 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 PROBLEMS 89 given mass flow? The specific heat ratio y is 1.4, and the molecular weight M is 30.
