R-134a expands through a throttling device from 900 kPA and 30 oC to -10 oC.
a- determine the entropy generation of this process.
b- the working fluid R-134a, this time expands adiabatically through a low pressure turbine with 90% isentropic efficiency from 900 kPa and 30 oC to -10 oC. What is the power generated by this turbine per unit mass flow rate of R134-a, in kj/kg.

Refrigerant R-134a enters the compressor of a refrigeration machine at 140 kPa pressure and -10 ° C temperature and exits at 1 MPa pressure. The volumetric flow of the refrigerant entering the compressor is 0.23 m3 / minute. The refrigerant enters the throttling valve at 0.95 MPa pressure and 30 ° C, exiting the evaporator as saturated steam at -18 ° C. The adiabatic efficiency of the compressor is 78%. Show the cycle in the T-s diagram. In addition, a)...
