An air-water vapour mixture enters an air- conditioning unit at 110 kPa, 30 0C, with a relative humidity of 50%. The mass flow rate of dry air entering the unit is 1 kg/s. The air-vapour mixture leaves the air-conditioning unit at 105 kPa, 10 0C, with a relative humidity of 100% and liquid condensate also leaves the unit at 10 0C. Determine the rate of heat transfer for this process
