Problem 25HP

Nozzles, Diffusers

Superheated vapor ammonia enters an insulated nozzle at 30°C, 1000 kPa, as shown in Fig. P4.25, with a low velocity and at a rate of 0.01 kg/s. The ammonia exits at 300 kPa with a velocity of 450 m/s. Determine the temperature (or quality, if saturated) and the exit area of the nozzle.
