Find the total entropy change(kJ/kg K). (Consider both the air in the nozzle and the surroundings.)
Assume that you have a nozzle, with air entering at 300 kPa and 67 C with a velocity of 60 m/s. The air exits the nozzle at 90 kPa and 330m/s. Do NOT make an adiabatic assumption. Instead, assume that the heat losses from the nozzle to the surroundings are 3.2 kJ/kg. The surroundings are at 20 C. Assume that air is an ideal gas with variable specific heats
.a) Find the exit temperature.
