2. 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, and (b) the exit area, in m2.

i don't understand really? can u provide more information

u should make a machine that can make ice cream fresh!
