Steam enters a heat exchanger at a pressure of 1.5 bar and a temperature of 400°C with a mass flow rate of 0.05 kg/s and exits a
t a temperature of 120°C and at the same inlet pressure. The steam heat transfer takes place with refrigerant R22 in a separate stream. The refrigerant enters the heat exchanger as liquid at 4.5 bar and leaves at the same pressure and at a temperature of 10°C. The heat exchanger is not well designed and there is stray heat transfer to the surroundings equal to 10% of the heat transferred from the steam.
Determine
(a) The rate of stray heat transfer, in kW.
(b) The rate of heat transfer to the refrigerant, in kW
(c) The mass flow rate of the refrigerant, in kg/s
