Standard Dry Air
Standard Dry Air is a standard
gas compositionfor 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 vapourentirely, since the humidityand the temperaturewill determine the amount of water vapour that can be present in air. This standard is used in flow measurementcalculations.
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.
