Acondenser of a heat pump uses r-134a as a working fluid. the fluid enters the condenser (after leaving the compressor) at a pressure of 120 psia and 140 f and a volume flow rate of 1.5 ft3/s.
the condenser cools the r-134a to a temperature of 90.49 f and a quality of 50% at the same pressure as it entered.
based on steady flow through the condenser what is the heat flow rejected to the outside air in btu/s to three significant digits?
