Re: Pressure drop Calculation.

First, you have to enter absolute, not gauge pressure.
Check the pipe diameter that you are entering, as well as critical pressure and temperature for LPG.
Also, select to enter w (on the right side of the calculator) and then enter mass flow rate.
Hope this helps.

Re: What is the assumed pipe material for the natural gas calculator?

Natural gas calculator is for up to 100 bar so it is surely steel pipe.

Re: Flow between the Vessels

I have used my calculator for gas flow on pipeflowcalculations.com. As you say the fluid is air than one can use air pressure drop calculator available on the same web site. I have divided the process into segments: A. What I have done is calculate flow rate for 12 bar inlet and 6 bar outlet. B. Aft...

Re: Flow between the Vessels

This type of calculation requires differential equation solution, meaning it is not an easy task, because the pressure on the exit of the pipe line is changing from 6 bar to 12 bar, and flow through connecting pipeline slows every moment. As you want to fell 5000 m3 tank through 1" pipe - I can tell...

Re: Calculating Pressure Drop in Natural Gas Piping

Hi,
Yes. That formula is ideal for your problem.
You are also free to download and try natural gas calculator that will help you on the calculation.

If you give me actual flow rate or burner power I can help you on calculation.
