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].

a) cold, dry

explanation:

continental polar masses are cold and dry air masses because the cold air cannot hold much moisture. as they move into warmer air, they can trigger precipitation.
