Steam at 0.8 MPa, 460°C, and 80 m/s enters an adiabatic nozzle at a rate of 0.04 kg/s. The pressure at the exit of the nozzle is 0.14 MPa. Find a. The exit velocity assuming a reversible process. b. The exit velocity assuming an isentropic efficiency of 0.75. c. The inlet and exit cross-sectional areas for cases a and b.
