Compressible Fluid Flow Calculation
Compressible Fluid Flow Calculation
(OP)
Hi,
Recently I came across a copy of "Gas-Flow Calculations: Don't Choke from Trey Walters" that describes the behavior compressible fluids undergo as they travel down the line. He describes a series of steps and iterations to carry out in order to come up with an accurate solution to determining the mass flow rate of a gas in a pipe.
On the other hand I found a relationship for short lines(very simplified) in the latest edition of rules of thumb for chemical engineers.
Any leads on this? is there a "mid-point" between the very daunting task of having to divide the line and analyze each one of the divisions and the simplified version of the exercise?
Any help will be highly appreciated.

Get a flow program that will do gas pipelines.
Stoner Pipeline Simulator,
Pipeline Studio,
Olga2000,
Hire a consultant that knows one of the above.

As far as software is concerned. If you are worried about choke flow, then you have to specifically ask the software vendor if their software support choke flow. Most don't.

I'd be more than happy to get a hold of some software to do the calculation however with the current economic downturn it is difficult to do since our corporate office cut our budget.
I think aft.com's compressible flow estimator should be able to carry out this calculation.

I am involved with Korf (www.korf.co.uk) and knows for a fact that it handles compressible choke flow correctly.
