Vg= V*P/T
Where:
Vg is the volume of natural gas in standard cubic meters
V is the volume of natural gas measured at the operating conditions (cubic meters)
P is the pressure of natural gas at operating conditions (atmospheres)
T is the temperature of natural gas at the operating conditions (Kelvin)
The ideal gas law can be used to calculate Vg as follows:
Vg = Vm * P1 / P2 * T2 / T1
Where:
Vg is the volume of natural gas in standard cubic meters
Vm is the volume of natural gas in cubic meters at the operating conditions
P1 is the standard pressure, which is 1 atmosphere
P2 is the operating pressure, in atmospheres
T1 is the standard temperature, which is 273.15 Kelvin
T2 is the operating temperature in Kelvin
