Using a psychrometric diagram, depict the heating and humidification process from the following data, Initially the air is at dry bulb temperature (DBT) 40 ° C and RH 50%. The air is heated to DBT 90 ° C. The heated air is then flowed through a humidifier to increase the RH to 25%. For this process, calculate a Change in the absolute humidity of the air from initial to final conditions = ... (kg of water / kg of air) b. The change in air enthalpy from initial to final conditions = ... (kJ / kg air)
