Question: Refrigerant-134a at 700 kPa, 70C, and 8 kg/min is cooled by water in a condenser until it exists as a saturated liquid at the same

Refrigerant-134a at 700 kPa, 70°C, and 8 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.
