Interpolation of the data in this part for airflow rates between 7,000 dscfm and 1,000,000 dscfm must use the equation:
c = 1.7627 x FRcorrected-0.3241
where:
c = concentration limit in gr/dscf
FRcorrected = gas volume in dscfm
aDry standard cubic feet per minute
bGrains per dry standard cubic foot.
