A refrigerator with tetrafluoroethane as refrigerant operates with an evaporation temperature of 247.15 K (-26°C) and a condensation temperature of 300.15 K (27°C). Saturated liquid refrigerant from the condenser flows through an expansion valve into the evaporator, from which it emerges as saturated vapor. For a cooling rate of 5.275 kW, what is the circulation rate of the refrigerant?
