Refrigerant-134a enters an adiabatic compressor

Refrigerant-134a at 700 kPa, 70째C, 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 15째C and leaves at 25째C at the same pressure. Determine the mass flow rate of the cooling water required to cool the refrigerant.
