Refrigerant-134a enters a compressor at 180 kpa as a saturated vapor with a flow rate of 0.35 m3/min and leaves at 900 kpa. the power supplied to the refrigerant during the compression process is 2.3 kw. what is the temperature of r-134a at the exit of the compressor?

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet
