Oxygen in air formula
Webtank. The SOR value is used to determine the air demand required to deliver sufficient oxygen to the process liquid. The air demand, given in terms of standard cubic feet per minute (scfm), is calculated by accounting for the specific weight of air at standard temperature, as well as the mass fraction of oxygen in air. WebThe density of air or atmospheric density, denoted ρ, is the mass per unit volume of Earth's atmosphere.Air density, like air pressure, decreases with increasing altitude. It also changes with variation in atmospheric pressure, temperature and humidity.At 101.325 kPa (abs) and 20 °C (68 °F), air has a density of approximately 1.204 kg/m 3 (0.0752 lb/cu ft), according …
