Flow Calculations

Flow Calculations

(OP)
How do I calculate for the following:
Two phases of flow (water and air runned in an incline pipeline from point 1 to point 2.  Point 1 P1=200psig, T1=180F, Q water=300GPM, Q Methane=300ACFM.

I need to calculate Q water, Q gas actual ACFM, and Q gas standard SCFM. at Point 2 assuming P2=50psi and T2=175F ??

How would the calculation change if instead water, oil were flown?  

RE: Flow Calculations

If its steady state, as much as 2-phase can be steady state, you already have the answer, just convert that methane flow to STP for the standard flow and to actual P & T at point 2 for the actual flow.  Water is the same.
If you're after the flow regime, you need the diameter, length and incline angle of the pipe before you can predict.

If the flows of oil and gas were the same as the water and air, you do it the same way.

RE: Flow Calculations

That brings back memories of college Thermo classes and High school PV/T ratios in Physics class.  

Been a long time...

RE: Flow Calculations

Right.  As it only invoked distant memories, I thought it could still be a real world problem ... maybe.  Well possibly.  Thus I didn't "student post" flag it ... just yet.
