Options
Standard
- 1985
The calculation is performed in accordance with AGA8 – 1985.
- 1994
The calculation is performed in accordance with AGA8 – 1994.
Add neo-Pentane to
- iPentane
- nPentane
This option is used to select which component the neo-pentane mole fraction is added to since it is not explicitly handled by AGA Report no. 8.
Calculation
AGA8 – 1985/1994 is calculated to the requirements of the international standard issued in 1985/1994 by the American Gas Association Transmission Measurement Committee.
Density and Compressibility Factor are calculated in accordance with the Detail Characterisation method within this standard.
Note: The list of inputs contains neoPentane a component not included in the AGA 8 report. The convention of adding this value to the iPentane during normalisation is adopted by this calculation, a practice commonly used in flow computers.
