# Volume of Air Required At Standard Conditions

Posted by Dinesh onUse the simple aerobic digester calculator tool to calculate the volume of air required at standard conditions for your wastewater problems. The volume of air required at standard conditions of 14.7 lb/sq in and 68 F with 23.2 percent oxygen by weight and a density of 0.075 lb/ft^{3} is: `(W`

._{O2}) / (0.075 lb/ft^{3}) * (0.232)

### Formula:

Volume of air (ft^{3}) = (W_{O2}) / (0.075 lb/ft^{3}) × (0.232)

W

_{O2}- Weight of oxygen
