Homework Question 1:

4.24 WP Nitrogen, modeled as an ideal gas, flows at a rate of 3 kg/s through a well-

insulated horizontal nozzle operating at steady state. The nitrogen enters the nozzle

with a velocity of 20 m/s at 340 K, 400 kPa and exits the nozzle at 100 kPa. To

achieve an exit velocity of 478.8 m/s, determine

a. the exit temperature, in K.

b. the exit area, in m².
