Determine the mass flow rate of the refrigerant flowing through the condensor of a two-stage compression refrigeration cycle (in kg/s). The fraction of the refrigerant that evaporates as it is throttled to the flash chamber is 0.19. The enthalpy of the refrigerant entering the evaporator is 55.14 kJ/kg and the enthalpy of the refrigerant leaving the evaporator is 239.19 kJ/kg. The amount of heat removed from the refrigerated space is 28 kW. (Round your answer to three decimal places).
Solution:- The given problem has been solved by drawing the schematic diagram of the the two stage compression refrigeration system. This diagram has helped in determining the various states of the refrigerant as it passes through the various elements of the system.
