The refrigerant fluid(Freon 12 or R12) flowing through the pipe with a pressure of 1 MPa and a temperature of 80oC is cooled to 1MPa pressure and 30oC with the air passed through the pipes in a condenser. The air at a flow rate of 800 m3/min enters the condenser at 100 kPa pressure and 27oC temperature and exits at 95 kPa pressure and 60oC temperature. Calculate the mass flow of refrigerant.
