AGA P_avg + Beggs-Brill Z + Wichert-Aziz Sour Correction
Compute gas inventory ("line pack") in a transmission pipeline at operating P, T. Uses AGA average-pressure formula (more accurate than arithmetic mean) and a real-gas Z-factor with Wichert-Aziz sour correction. Working pack vs minimum operating P available if specified.
