A condenser 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?
