Unformatted text preview: 2 , and a velocity of 20 ft/s. At the nozzle exit the temperature is 200F, the pressure is 5 lbf/in 2 , and the fluid velocity is 1100 ft/s. (a) Determine the nozzle area (ft 2 ) at the inlet and exit. (b) Determine the rate of heat transfer (Btu/s) between the nozzle and the surroundings. SP19: Refrigerant 134a enters a well-insulated compressor as a saturated vapor at -26C with a volumetric flow rate of 0.5 m 3 /s. The R134a exits the compressor at a pressure of 9.0 bar and a temperature of 75C. (a) Determine the mass flow rate (kg/s) through the compressor. (b) Determine the volumetric flow rate (m 3 /s) at the compressor exit. (c) Calculate the compressor power (kW)....
