5-146E Refrigerant 134a enters an adiabatic compressor at 15 psia and 20F with a volume flow rate of 10 ft/s and leaves at a pressure of 100 psia. The power input to the compressor is 45 hp. Find (a) the mass flow rate of the refrigerant and (b) the exit temperature. P = 100 psia R-134a P = 15 psia T = 20F V = 10 ft/s 45 hp
