Question: Steam enters a converging nozzle at 3.0 MPa and 500C with a negligible velocity, and it exits at 1.8 MPa. For a nozzle exit area

Steam enters a converging nozzle at 3.0 MPa and 500°C with a negligible velocity, and it exits at 1.8 MPa. For a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit Mach number if the nozzle (a) is isentropic and (b) has an efficiency of 90 percent.
