Air at 1 bar and 25°C continuously flows through a rigid compressor at a low velocity of 1 m/s. The air exits the compressor at 3 bar, and then enters a nozzle in which it expands adiabatically to a final velocity of 600 m/s at the initial conditions of temperate and pressure. Assume no change in elevation, and that the inlet and outlet conditions are constant with time. If the compressor transfers 240 kJ/kg of mechanical work to the air, how much heat must be removed from the compressor?
I am completely confused. Adiabatic means no heat transfer?.. Please help
