Pack In Pipeline

Calculates using gas packed in an isolated section of the pipe. It uses PLTB Gas Lost in a Full-Bore Rupture calculation in the Accidental Release Module.
Upstream and downstream pressures must be known at the time of calculation. In addition, the actual internal diameter and gas temperature can change the results for accounting purposes.,
