In a heat-driven refrigerator with ammonia as the working fluid, a turbine with inlet conditions of 2.0

Question:

In a heat-driven refrigerator with ammonia as the working fluid, a turbine with inlet conditions of 2.0 MPa, 70◦C is used to drive a compressor with inlet saturated vapor at −20◦C. The exhausts, both at 1.2 MPa, are then mixed together, as shown in Fig. P7.107. The ratio of the mass flow rate to the turbine to the total exit flow was measured to be 0.62. Can this be true?
