John,

I might not understood your question correctly, but I will attempt to answer. So please double check my figures...

Let's say you have a 10L 200bar supply tank of Helium. That's is (10)(200)=2000 free liters of Helium available.

If you want 132 liters in your 3L Rebreather tank, and assuming it is completely empty to begin with. You simply connect the whip and stop when the pressure is (132)/(3)=44 bar in the 3L tank.

The pressure in your supply tank is now... (2000)-(132)=(1868) liters/(10)=186.8 bar.

Is this something you are looking for, or something else ?

I think I said that in my post #7, thanks for the reply and the confirmation. It is a shame that there are always a few numpties that might not know the answer to a question but they HAVE to put their oar in!

Hey Thanks!

I got involved because i thought Steve's response was a little sharp.
But your obviously right that i wouldn't now the answer
Lets see !!!!!!

would it have been covered on my hse part 1 course in 89 (maybe)

How about my hse part 2 saturation course in 92 (possibly)

How about on the first completed ccr mod 3 course in the uk 99 ?????????????

Maybe i got all my cylinder fills wrong on the egypt wreck in 2001 and on the discovery of the Flying enterprise on the way back AND COUNTLESS MID CHANNEL WRECK DIVES

On 1000's of dives i guess i've been bluffing it!!!!!

I mean ive only been doing this shit 29 years so what could i know

Yours in awe
