Standard Dry Air

Standard Dry Air

Standard Dry Air is a standard gas composition for dry air, intended to represent the bulk average air composition encountered at or around sea level. Despite its intent of being near sea level, the composition omits water vapour entirely, since the humidity and the temperature will determine the amount of water vapour that can be present in air. This standard is used in flow measurement calculations.

The most important point to note about standard dry air is that its mixture molar mass is 28.9625 g/mol. You can contribute to this article by specifying what standards body defines standard dry air, and the name of the standard.
