13 thermodynamics

As shown in the figure, Refrigerant 22 enters the compressor of an air conditioning unit operating at steady state at 40°F, 80 lb/in²
and is compressed to 160°F, 200 lb/in2. The refrigerant exiting the compressor enters a condenser where energy transfer to air as a
separate stream occurs, and the refrigerant exits as a liquid at 200 lb/in2, 90°F. Air enters the condenser at 75°F, 14.7 lb/in² with a
volumetric flow rate of 1250 ft3/min and exits at 110°F. Neglect stray heat transfer and kinetic and potential energy effects, and
assume ideal gas behavior for the air.
