Humid air at 25 oC and 80% relative humidity is cooled and dehumidified at atmospheric pressure, and then reheated and brought to 20 oC and 40% relative humidity. Analysis will be done by drawing on the psychometric diagram.a) What is the amount of water removed from the humid air (kg water / kg dry air)? b) What is the heat withdrawn from moist air (kJ / kgdry air)? c) What is the heat (kJ / kg dry air) given from the heater to the humid air?
