The following additional information applies to the various steps of the process: The compression step is irreversible, with a power consumption of 900.0 W The refrigerant leaves the condenser as a saturated liquid The stream leaving the valve has a quality of 38% 1 Water is used in the adiabatic heat exchanger at a rate of 120.0 kg/hr. It does not mix with the refrigerant in the cycle a. Correctly match the stream numbers in the flow diagram (1-4) with the points on the P-v plot. [3] b. Calculate the specific heat of condensation [icon (b)] for R-40 at the temperature that it leaves the heat exchanger. [6] c. Calculate the mass flowrate [kg/hr) of R-40 in the cycle. [8] d. What is the maximum temperature of the stream leaving the compressor?
