Steam at 5 MPa and 500°C enters a nozzle at a rate of 25 kg/s at a speed of 40 m/s, and leaves at 200 kPa and x = 0.92.

a. Find the exit velocity.

b. Find the cross-sectional areas at the inlet and outlet of the nozzle.

c. Find the entropy change across the nozzle.

d. What is the isentropic efficiency of the nozzle?
