I tried to search the forum without success.
How do I calculate the storage volume of air in a cylinder given the pressure range and the size.
Example if i want to work out which will give more charges between 2 cylinders of different size and working pressures:
1) A 6L cylinder going from 300 bar to 150 bar (150 bar working range) and
2) A 10L cylinder going from 200 bar to 150 bar (50 bar working range)
I would appreciate a formula which i could work these out and extrapolating it to 232 bar tanks with a different size etc.
