1. Saturated water vapor at 150.°C enters an isentropic converging nozzle with a negligible velocity and exits at 0.300 MPa. Determine the exit quality, temperature, and velocity. Do not assume ideal gas behavior.
2. Air flows in a circular tube with a velocity of 275 ft/s at a temperature of 103°F and a pressure of 175 psig. Determine its stagnation pressure and temperature.
