Refrigerant-134a at 700 kPa, 70°C, and 7.2 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.
