Refrigerant-134a enters an adiabatic compressor as saturated vapor at 100 kpa at a rate of 0.7 m3/min and exits at 1 mpa pressure. if the isentropic efficiency of the compressor is 87 percent determine: (a) the temperature of the refrigerant at the exit of the compressor, and (b) the power input, in kw. also, show the process on a t-s diagram with respect to saturation lines.
