An air–water vapor mixture enters an air-conditioning unit at a pressure of 150 kPa, a temperature of 30° C, and a relative humidity of 80%. The mass flow rate of dry air entering is 1 kg/s. The air–vapor mixture leaves the air conditioning unit at 125 kPa, 10° C, and 100% relative humidity. The condensed moisture leaves at 10° C. 

Determine the heat-transfer rate (kW) for this process.
