A drier is to be designed to reduce the water content of a certain material from 55% to 10%. Air at 29 C dry bulb temperature and with a humidity ratio of 0.005 kg/kg is heated to 50 C in a reheater before entering the drier. The air leaves the drier at 38 C with 70% relative humidity. On the basis of 1000 kg of product per hour, calculate (a) the volume flow rate of air entering the reheater, and (b) the heat supplied in the reheater.

Using a psychrometric diagram, describe the heating and humidification process from the following data. Initially the air was at dry bulb temperature (DBT) 30 ° C and RH 35%. 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 enthalpy of air from initial to final conditions = ... (KJ / Kg of air)
