7. Refrigerant 134a is compressed at steady state from saturated vapor at -20°C to 7 bar, and 70°C. Mass flow rate is 1.2 kg/s. Neglect kinetic and potential energy effects. Determine (a) the volume flow rates at the inlet and exit, each in m3/s, (Hint: obtain specific volume from given conditions using tables and then the given mass flow rate to get volume flow rates -similar to turbine example) and (b) the power input to the compressor, in kW.
