18  Mass fraction of carbon dioxide in a re‑routed gas quantity
  The mass fraction of carbon dioxide in the re‑routed gas quantity in relation to a flare device is worked out using the formula (equation 5):
where:
mCO2,i% means the mass fraction of carbon dioxide in the re‑routed gas quantity in relation to flare device i, in mass%.
molCO2,i% means the molar fraction of carbon dioxide in the re‑routed gas quantity in relation to flare device i, in mol%, worked out:
 (a) if, under section 34, the project proponent has chosen to use historical sampling data in relation to the reporting period—using that data; or
 (b) otherwise—in accordance with the monitoring requirements.
mwCO2 means the molecular weight of carbon dioxide, in kilograms per kilomole, set out in the table in subsection 2.22(3) of the NGER (Measurement) Determination.
V means the volume of 1 kilomole of a gas at standard conditions, which is 23.6444 cubic metres.
dTOTAL,i means the density of the re‑routed gas quantity in relation to flare device i, in kilograms per cubic metre, worked out using equation 7.
