A flow of air at 10◦C, φ = 90% is brought into a house, where it is conditioned to 25◦C, 60% relative humidity. This is done with a combined heater-evaporator in which any liquid water is at 10◦C. Find any flow of liquid and the necessary heat transfer, both per kilogram of dry air flowing. Find the dew point for the final mixture.
