Refrigerant-134a at 700 kpa, 70°c, and 8.6 kg/min is cooled by water in a condenser until it exists as a saturated liquid at the same pressure. the cooling water enters the condenser at 300 kpa and 15°c and leaves at 25°c at the same pressure. determine the mass flow rate of the cooling water required to cool the refrigerant. the enthalpies of r-134a at the inlet and exit states are 308.34 kj/kg and 88.82 kj/kg. the enthalpies of compressed water at both states are 62.98 kj/kg and 104.83 kj/kg.
