How To Calculate the GCF for Pure Gases
To calculate the Gas Correction Factor for
pure
gases, use the following equation:
GCF =
(0.3106) (s)
(d ) (cp )
x
xx
where:
GCF
x
= Gas Correction Factor for gas X
0.3106 = (Standard Density of nitrogen) (Specific Heat of nitrogen)
s = Molecular Structure correction factor where S equals:
1.030 for Monatomic gases
1.000 for Diatomic gases
0.941 for Triatomic gases
0.880 for Polyatomic gases
d
x
= Standard Density of gas X, in g/l (at 0° C and 760 mm Hg)
cp
x
= Specific Heat of gas X, in cal/g° C
