Question:

Air enters the adiabatic nozzle of a turbojet engine at 230 kPa, 600°C with a velocity of 60 m/s as shown in Figure P3.7. At the nozzle exit, the air is at 70 kPa, 450°C.
The dead state is 100 kPa, 20°C. Determine the following information,

a. The exit velocity of the air (m/s)

b. The isentropic efficiency of the nozzle

c. The exergy destruction per kg of air flowing through the nozzle (kJ/kg)

d. Devise and calculate an exergetic efficiency for the nozzle image text in transcribed
