Refrigerant-134a at 900 kPa and 75oC, and 9.5 kg/s is to be cooled by water in an insulated condenser until it exits as a saturated liquid at the same pressure. The cooling water enters the condenser at 290 kPa and 11oC, and leaves at 32oC at the same pressure. Neglecting any heat losses, determine
(a) The mass flow rate of the cooling water.
(b) The entropy generation rate in the system.
