Capacity of O2 gas in a cylinder
Capacity of O2 gas in a cylinder
(OP)
Hello,
I want to know how can I calculate the volume capacity of O2 gas in a cylinder when the gas is in 2524 psi with a room temperatura (70°F).
thanks in advance

If you expand the oxygen quickly, it will come out cold and take up quite a bit less volume than you might otherwise expect until it warms back up again.

a) The Redlich Kwong equation
b) The Benedict Webb Rubin equation
Methods for these can be found in 6th edition of Perry Chem Engg Handbook in the section on physical properties estimation - a lot of this material (especially the BWRS EOS) is excluded in the 7th edition. Since O2 is paramagnetic, would suspect it deviates more than say nitrogen from z=1 at high pressures.

There is sadly no universal "standard" conditions to which you reference back to. This has been debated a LOT on these pages so I won't start it up again now.
Seems to be a very precise pressure reading....
Also depends on what is your end pressure if you're trying to work out usable volume

Just to know in what source Can I get the z values for different kinds of gases, like N2,Ar, Helium, Air in different pressures?

You can also build your own spreadsheet because the EOS' are not that complex.

select O2
print the whole table for your office wall paper.

It's a much rounder number when you convert it to bar (same as people are always asking me why our systems run at 276 bar).
By the way, can I be really nosy and ask BigInch - LittleInch: Any relation?

I hate it when nominal figures get converted exactly and not rounded.
No one bit on the standard volume question though....

We usually agree on everything ... eventually. Well ... except for the spelling of certain words.

Why do we want to know?
276 barg = +/- 4000 psig
RE: Capacity of O2 gas in a cylinder
So pretending to have a pressure accurate to 1psi is a non starter to begin with.
Charts like this already tell you how much you get out of a cylinder....
