Solve for mas flow rate, and compressor power in horsepower. Step by step solution please thank you As shown in the figure, Refrigerant 22 enters the compressor of an air conditioning unit operating at steady state at 40°F, 80 lb/in2and is compressed to 160°F, 20O Ib;/in?. The refrigerant exiting the compressor enters a condenser where energy transfer to air as aseparate stream occurs, and the refrigerant exits as a liquid at 200 lb;/in?, 90°F. Air enters the condenser at 80°F, 14.7 Ibf/in? with avolumetric flow rate of 1000 ft/min and exits at 110°F. Neglect stray heat transfer and kinetic and potential energy effects, andassume ideal gas behavior for the air.Condenser5wwww4+Air at T4 P4=14.7lbfin?(AV),I;=110°F|3P2 = p3 = 200 Ibyin²wwwT2= 60°F2-T= 160°FP2=200 lbfin_?T3- 90°FP=200 Ibf/in²T3= 90°Fpi = 80 Ibrin?CompressorT1= 40°F1+ R22 atIz=40°FPi - 80 Ibf/in.?Determine the mass flow rate of refrigerant, in Ib/min, and the compressor power, in horsepower.
