Passed through a dehumidifier to reduce its relative humidity to 10%. Clearly show the various paths of the process on a psychrometric chart. The air velocity through the bed and the dehumidifier is 4 m/s and the cross-sectional diameter of the bed is 0.5 m. a. Determine the amount of moisture removed, in grams of water/second from the apricot bed. b. Determine the amount of moisture removed, in grams of water/second in the dehumidifier.
