Convert flowrates to nitrogen volume fractions (%)

Calibrated Values of Nitrogen Flowrate

The flowrate is converted to nitrogen volume fraction (%), Z, where

and C = 10 LPM for air is considered to be a constant.

Values For New Flux Measurements

Applying these formulas to the new flux measurements results in the following table:

       MEASURED      PREDICTED               
           FLUX           FLOW              Z
