The air has a dry ball temperature of 32 ° C and a wet bulb temperature of 24 ° C is initially heated in a heater so that the dry ball temperature increases to 80 ° C. Then the air is passed through the pile of corn kernels to dry. The air that comes out of the corn kernels is at a dry bulb temperature of 55 ° 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 airflow rate through the corn kernels pile and dehumidifier is 3.0 m / s and the cross-sectional diameter of the pile is 0.7 m. a. Determine the amount of water lost from the corn kernels heap (in grams of water / second) = .... (grams of water / second). b. Determine the amount of water lost from the air when passing through the dehumidifier (in grams of water / second) = .... (grams of water / second

Question
The air has a dry ball temperature of 32 ° C and a wet bulb temperature of 24 ° C is initially heated in a heater so that the dry ball temperature increases to 80 ° C. Then the air is passed through the pile of corn kernels to dry. The air that comes out of the corn kernels is at a dry bulb temperature of 55 ° 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 airflow rate through the corn kernels pile and dehumidifier is 3.0 m / s and the cross-sectional diameter of the pile is 0.7 m.
a. Determine the amount of water lost from the corn kernels heap (in grams of water / second) = .... (grams of water / second).
b. Determine the amount of water lost from the air when passing through the dehumidifier (in grams of water / second) = .... (grams of water / second
