Question:

In a heat-powered refrigerator, a turbine is used to drive the compressor using the same working fluid. Consider the combination, where the turbine produces just enough power to drive the compressor and the two exit flows are mixed together.
List any assumptions made and find the ratio of mass flow rates m3/m1 and T5 (x5 if in two-phase region) if
a. The turbine and the compressor are reversible and adiabatic
b. The turbine and the compressor both have an isentropic efficiency of 70%
