Using a psychrometric diagram, describe the heating and humidification process from the following data. Initially the air was at a dry bulb temperature (DBT) of 30 ° C and RH60%. The air is heated to DBT 80 ° C. The heated air is then flowed through a humidifier to increase the RH to 25%. For this process, calculate,a. Change in absolute humidity of air from initial to final conditions = (kg water / kg air).b. The change in air enthalpy from initial to final conditions. = (kJ / kg air)
