Air and fuel enter a turbojet engine (turbine) having an enthalpy of 800 kJ/kg and arelative velocity is 15 m/s. The mixture exits with a relative velocity of 60m/s and an enthalpy of 650 kJ/kg. The mass flow rate is 30 kg/s, and the rate of heat loss is 1.5 kJ/s. what is the power output of the engine?

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
