Refrigerant 134a at 1 MPa and 90oC is to be cooled to 1 MPa and 30oC in a condenser by air. The air enters at 100 kPa and 27 oC with a volume flow rate of 600 m3/min and leaves at 95 kPa and 60oC. Determine the mass flow rate of the refrigerant. [R=0.287 kPa. m3/kgK][Use specific heat values at room temperature].

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
