A small expander (a turbine with heat transfer) has 0.05 kg/s helium entering at 1000 kPa, 550

Question:

A small expander (a turbine with heat transfer) has 0.05 kg/s helium entering at 1000 kPa, 550 K and it leaves at 250 kPa, 300 K. The power output on the shaft is measured to 55 kW. Find the rate of heat transfer neglecting kinetic energies.
