The air has a dry ball temperature of 40 ° C and a wet bulb temperature of 20 ° 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.

Question
The air has a dry ball temperature of 40 ° C and a wet bulb temperature of 20 ° 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 and dehumidifier was 6.0 m / s and the pile cross-sectional diameter was 0.7 m.
