Question:

Ammonia enters a nozzle at 800 kPa, 50C, at a velocity of 10 m/s and at the rate of 0.1 kg/s. The nozzle expansion is assumed to be a reversible, polytropic SSS F process. Ammonia exits the nozzle at 200 kPa; the rate of heat transfer to the nozzle is 8.2 kW. Verify that the exit temperature is close to -10C. What is the velocity of the ammonia exiting the nozzle?
