IMPORTANT These tables are provided for reference only. We encourage you to independently verify all calculations. SeQual assumes no liability for errors which may result from using the conversion factors above. All calculations are based upon standard temperature and pressure (STP). Some unit systems may base pressure and flow, and density measurements on other conditions. We encourage you to consult a reference manual when performing calculations to size your system. Oxygen mass flow calculations assume an oxygen-enriched gas mixture (90% O2 - 5% Ar - 5% N2) with a density of 0.0833 lb/ft3 (1.334 kg/m3). Nitrogen mass flow calculations assume a nitrogen density of 0.0725 lb/ft3 (1.153 kg/m3). Gas densities are dependent upon pressure, temperature, purity, and ambient conditions. Please consult a reference manual when verifying conversion factors. In order to derive relationships between various factors, enter a 1 in the unit you wish to reference to all others and hit the calculate button.
