e air has a dry ball temperature of 30 ° C and a wet bulb temperature of 22 ° C is initially heated in a heater so that the dry ball temperature increases to 90 ° C. Then the air is passed through the corn kernels to dry. The air that comes out of the corn kernels is at a dry bulb temperature of 60 ° C. Then this air is passed to the dehumidifier to reduce the RH to 10%. Draw the course of this process of changing the air on a psychrometric diagram. The air flow rate through the corn kernels and dehumidifier is 2.0 m / s and the diameter of the pile holder is 0.5 m. a. determine the amount of water content lost from the pile of corn kernels (in grams of water / second) = answer (grams of water / second). b. determine the amount of water lost from the air when passing through the dehumidifier (in grams of water / second) = answer (grams of water / second)

The air has a dry ball temperature of 30 ° C and a wet bulb temperature of 22 ° C is initially heated in a heater so that the dry ball temperature increases to 90 ° C. Then the air is passed through the corn kernels to dry. The air that comes out of the corn kernels is at a dry bulb temperature of 60 ° C. Then this air is passed to the dehumidifier to reduce the RH to 10%. Draw the course of this process of changing the air on a psychrometric diagram. The air flow rate through the corn kernels and dehumidifier is 2.0 m / s and the diameter of the pile holder is 0.5 m. a. determine the amount of water content lost from the pile of corn kernels (in grams of water / second) = answer (grams of water / second). b. determine the amount of water lost from the air when passing through the dehumidifier (in grams of water / second) = answer (grams of water / second)
