Specific Gravity (or Relative Density)
The
Dry Specific Gravity
and
Saturated Specific Gravity
of the gas are calculated using
equations 13-7 and 13-8:
Dry Specific Gravity
Dry SG = (
Σ
Pn=1
Conc
n
x SG
n
) / 100
13-7
Where:
Dry SG
= Dry Specific Gravity of the sample gas
Conc
n
= Normalized concentration of component n
SG
n
= Specific Gravity value of component n
P
= Number of components in the analysis
Saturated Specific Gravity
Sat SG = Dry SG*(1 – xw) + xw × 0.62202
13-8
Where:
Sat SG
= Saturated specific gravity of the sample gas
Dry SG
= Dry Specific Gravity of the sample gas
x
w
= molar fraction of water
Wobbe Index
The
Wobbe Index
and
Saturated Wobbe
Index is calculated using equations 13-9 and 13-10.:
Dry Wobbe Index
Dry Wobbe Index = (Corrected Dry BTU / ft
3
) / √(Dry SG)
13-9
Saturated Wobbe Index
Sat Wobbe Index = (Corrected Sat BTU / ft
3
) / √(Sat SG)
13-10
