Request: Nitrogen Termal expantion calculation

[Cains]

Hi does any of you geniuses have something to make the Calculations for Dome filling of ipo`s easier, Something that take the expansion factor of the nitrogen under temperature and pressure, Sorry if this is badly written but english is not my native language, Would really appreciate if someone had this.

Kind Regards

the question is not clear to me,
however if you need to calculate density at different temperatures & pressures for nitrogen or other gas in Excel you can use the Prode library (see "www.prode.com"), I suppose you know or can calculate the volume (there are easy formulations for almost all vessels) then knowing gas density with Excel you can calculate the total volume and mass required

Thanks alot Carlo for taking the time to answer my question, Prode.com is a new site for me to explore, im kind of new to gaslift and the uses of IPO`s but all calculations i do as for now is done by hand/Calculator, Using coficents for N2. and i really suck when it comes to making excell spread sheet. But i will definatly try, new motivation with the new siste. Again thanks alot.
