One evaporator is to provide 30 tons of refrigeration at-10 degree Celsius and another evaporator is to provide 15 tons at 0 degree Celsius. The condensing temperature is 40 degree Celsius, assuming saturated vapor is leaving the evaporator and saturated liquid in the condenser, determine: a The mass flow rate, in kg/s. b. The coefficient of performance of the system.
