If I have a 12l cylinder with 130bar of 23% in it & want to end up with a 32/10 trimix what do I need to add ?
According to 1 blending program I need to add 35 bar of O2 & 23 bar of He
using my other program I need 31bar O2 & 34 bar of He !:confused:
11 bar difference of He is a lot

I would agree with the first one but I could be missing something :redface:

Me thinks you've got these the wrong way round

i.e. 23 bar of He in 232 bar . . . 23 / 232 = .099, or 10% near as dammit

this was the logical figure that I worked out mathematically but I did wonder if I was missing something due to some obscure property of He .
The reason for the mix is for somebody who gets narked over 22m ish ,just reduces the END that little bit .:teeth:
