4. Using a psychometric diagram, describe the heating and humidification process from the following data. Initially, the dry ball temperature (DBT) was 35 ° C and RH 40%. The air is heated to DBT 85 ° C. The heated air is then flowed through the 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. change in enthalpy of air from initial to final conditions = (kj / kg air)
