Example 5-2 Saturated vapor refrigerant R134a at -25°C is compressed to a final pressure of 310 kPa. The efficiency of the compressor is 82%. Calculate the work input per unit mass flow in the compressor (in kJ/kg). Show the process on a T-s diagram. Solution: The ideal work input to the compressor is () 12 ideal s Wm h h =− ± ± 1 kJ enthalpy(R134a, 25, 1) 235 kg hT x == = = To find state 2s, we need the entropy at state 1
