Moisture Holding Capacity of Air

Moisture holding capacity of air increases with temperature

The moisture holding capacity of air increases dramatically with increased temperature as indicated in the diagrams below.

Air Moisture Holding Capacity - SI Units

Moisture holding capacity of air - kg water per kg dry air:

air moisture holding capacity si units

Air Moisture Holding Capacity - Imperial Units

Moisture holding capacity of air - lb water per lb dry air:

air moisture holding capacity si units

Moisture holding capacity of air - lb water per 1000 cubic feet dry air:

air moisture holding capacity si units

Note - 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 to transport moisture away from process and products.

In general

  • it is in general good energy economy to increase the air temperature in a dryer as much as possible! - the increased moisture transport capacity of air at higher temperature out-weights the increased energy-consumption for heating the dry air to higher temperature!
