Definition - What does Saturated Air mean?
Saturated air is air that holds water vapor at its highest level. Air is composed of moisture or water vapor, regardless of the amount of pressure and temperature levels. Adding more moisture to the air at a specific temperature and in an enclosed area causes the air to absorb the moisture.
Excess moisture leads to the formation of saturated air as brought about by the conversion of moisture into dew.
Corrosionpedia explains Saturated Air
Once a particular point is reached, the air can no longer hold moisture and all excess is converted to fog or dew. The air which consists of the highest moisture amount at a certain temperature is known as saturated air.
The amount of moisture that air is capable of holding relies on the temperature. The higher the air temperature, the higher the amount of moisture the air can absorb. Accurate measurement of saturated air levels is essential in preventing damaging effects due to corrosion. For instance, saturated air can be relied on to assess the comfort level in industries that make use of evaporators.
When the saturated air is too low, discomfort can result. This phenomenon leads to circulation of drier air that can lead to cracking in equipment such as pipes and barrels. In industrial operations that necessitate less cooling, a lower level of saturated air can result in effective cooling or evaporation.
