mostly horizontal with minor elevations and depressions. At around sea level

It is currently empty as it is undergoing commissioning activities. During operation, it will carry LPG.

So would that mean that a numeric simulation is the only way to determine the ballpark of the true velocity of air escaping the pipeline?

The scenario in question simulates a typical pipeline cleaning methodology that uses air blowing to compress a pipeline to a specific pressure until the rupture disc blows. The result is quick decompression of the line and the flushing out of debris or dirt that is resting in the pipeline. My...

What if, instead of a rupture disc, a quick release valve was used to release the pressure from the pipeline to the atmosphere. You can consider valve-opening to be instantaneous. Can we use Poiseulle's law or Bernoulli's principle to determine the exit velocity of the air

Suppose an isolated pipeline of known dimensions is being filled with air from the atmosphere (via a compressor) to a gauge pressure P1=2barg. A rupture disc at one end of the pipeline blows at this pressure, and the air inside the pressurized pipeline is released to the atmosphere. The rupture...
