As shown in the figure, Refrigerant 22 enters the compressor of an air conditioning unit operating at steady state at 40°F, 80 lb;/in? and is compressed to 160°F, 200 Ib;/in?. 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 Ib:/in?, 90°F. Air enters the condenser at 70°F, 14.7 lb:/in? with a volumetric flow rate of 750 ft/min and exits at 110°F. Neglect stray heat transfer and kinetic and potential energy effects, and assume ideal gas behavior for the air. Condenser Air at T P4=14.7 1bf'in.?

Refrigerant 134a enters an insulated diffuser as a saturated vapor at 80°F with a velocity of 1400 ft/s. The inlet area is 1.4 in². At the exit, the pressure is 400 lb/in² and the velocity is negligible. The diffuser operates at steady state and potential energy effects can be eglected. Determine the mass flow rate, in lb/s, and the exit temperature, in °F. Step 1 Your answer is correct. Determine the mass flow rate, in lb/s. m = 28.887 Hint Step 2 lb/s. Determine the exit temperature, in °F. T₂ = i OF Attempts: 1 of 4 used
