Yes. You will see Save button on the top menu, as well as Open button. The saved file will have .pfcx extension and it has all the information that you can reuse later on.

Actually, from today new version is available with an option to save and open saved files. Download the new version and let me know if you like it.

New version will have that functionality. I hope to release it in following days.

You should also know how many strokes you have in a min or hour? So you calculate a needed flow as a volume of the cylinder * number of strokes; Q = V * n, where is Q - is a flow, V - is volume, n - is a number of strokes in a unit of time. Another question is if you have a compressor to fill the ta...

It is not changing with the pressure or the temperature. It is constant for a certain gas. R in terms of J/kg K is calculated as Ru/M where Ru is universal gas constant for any gas and particular molar mass. Ru = 8.314 J/mol K. In your formula pV=nRT you are using Ru. in a pV=mRT or p/rho = RT formu...

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.

I would suggest you to use gas pressure drop calculator.

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