Solve the below problem:
Q: Steam enters an adiabatic nozzle at 3.5 MPa and 300°C with a low velocity and leaves at 1.6 MPa and 250°C at a rate of 0.4 kg/s. If the ambient state is 100 kPa and 18°C, determine
(a) the exit velocity,
(b) the rate of energy destruction, and
(c) the second-law efficiency.
