Question: Steam enters a converging nozzle at 450 psia and 900F with a negligible velocity, and it exits at 275 psia. For a nozzle exit area

Steam enters a converging nozzle at 450 psia and 900°F with a negligible velocity, and it exits at 275 psia. For a nozzle exit area of 3.75 in2, 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.
