Hot combustion gases enter the nozzle of a turbojet engine at 230 kPa, 627C, and 60 m/s
Question:
Hot combustion gases enter the nozzle of a turbojet engine at 230 kPa, 627°C, and 60 m/s and exit at 70 kPa and 450°C. Assuming the nozzle to be adiabatic and the surroundings to be at 20°C, determine
(a) The exit velocity
(b) The decrease in the exergy of the gases. Take k = 1.3 and cp = 1.15 kJ/kg·°C for the combustion gases.
