The moisture holding capacity of air varies with temperature
The moisture holding capacity of air increases dramatically with increasing air temperature.
Air Moisture Holding Capacity - SI Units
Moisture holding capacity of air - kg water per kg dry air:
Air Moisture Holding Capacity - Imperial Units
Moisture holding capacity of air - lb water per lb dry air:
Moisture holding capacity of air - lb water per 1000 cubic feet dry air:
Note that the moisture holding capacity of air at 100oF (38 oC) is 10 times the moisture holding capacity of air at 30oF (~ 0 oC). This is a very important observation - especially when working with drying processes where air is used for transport of moisture away from the process and the product.
- it is good energy economy to increase the temperature in a dryer as much as possible! - the increased moisture transport capacity of the air at a higher temperature will normally out weight the increased energy consumption for heating the dry air to a higher temperature!
