Question: Nitrogen flows through a well - insulated nozzle at 4 k g s . The nitrogen enters the nozzle at 2 5 m s at

Nitrogen flows through a well-insulated nozzle at 4kgs. The nitrogen enters the nozzle at 25ms at 27C and 400 kPa and exits at 100 kPa . The exit velocity is 450ms. Assume constant specific heats (at the entrance temperature). Find
a. The exit temperature of nitrogen.
b. The specific volume of the nitrogen at the entrance.
c. The specific volume of the nitrogen at the exit.
d. The exit area of the nozzle.
