Refrigerant-134a is to be cooled by water in a condenser. The refrigerant enters
the condenser with a mass flow rate of 6 kg/min at 1 MPa and 708C and leaves
at 358C. The cooling water enters at 300 kPa and 158C and leaves at 258C.
Neglecting any pressure drops, determine (a) the mass flow rate of the cooling
water required and (b) the heat transfer rate from the refrigerant to water
