Question
A certain product is being dried in a small chamber at 30°C wet bulb temperature and 43°C dry bulb temperature. The net drying rate of the product is 1.40 kg H2O(v)/h.
If outside air is saturated at 20°C:
(product is being dried but air is increasing in moisture content)
- What are the absolute humidities of the outside air and the one in the chamber?
- Determine the amount of water removed from the product per kg of Dry Air.
- How much outside air (/min) is needed to carry out the evaporation?
