Consider a refrigeration system that operates on an actual
vapor-compression refrigeration cycle with refrigerant-134a as the
working fluid with an isentropic efficiency of a compressor of
77.4%. The refrigerant enters the compressor as saturated vapor at
140 kPa and is compressed to 800 kPa. Determine the quality of the
refrigerant at the end of the throttling process, answer in 4
decimal places.
