## how to calculate the volume of PRESSURIZED Natural gas in a pipe

(OP)

Hello,

i need to know exactly how to calculate volume (to know the the time it will take till the pipe line will be empty)

for PRESSURIZED natural gas.

i was using Volume X pressure ( gauge pressure )

and then i have been told that i must use the absolute pressure.

please advice.

Thanks

Maybe you should seek help either within you company or external consultant?

A blowdown calculation is much more than just the inventory.

BTW: The VOMUME is just the volume of the pipeline - but the STANDARD volume is actually just the no. of mol gas in the pipeline - but thats not "jus" the volume.

Best regards

Morten

P2 * V2 /z2 /T2 = P1 * V1 / z1 / T1

V1 = P1/P2 * T2/T1 * z2/z1 * V1

There's more to consider than just volume.
