The air at the entrance to a grain dryer is 40.0 ° C and 20.0% RH. The debit

is 300.0 L / s. The dryer extracts 7,000 kg / h of grain water. The air temperature at

dryer outlet is 30.0 ° C. What is the relative humidity (%) of the air leaving the dryer?

The total pressure everywhere is 101.3 kPa.

Yes debit means flowrate of air entering.

Humid air is enclosed in a 5.00-liter flask at 40.0°C. The flask is slowly cooled. When the temperature reaches 20.0°C, drops of moisture become visible on the flask wall. Although the pressure in the flask changes when the temperature drops, it remains close enough to 1 atm for the psychrometric chart to provide a close representation of the behavior of the system throughout the process. Use a psychometric chart to determine the relative humidity, absolute humidity, and wet-bulb temperature of...
