Thanks for the explanation Morgan. See you in Youghal!
The question about calculations in rebreathers has been answered. You need to calculate the composition of the loop gas first, then apply the method described in the paper.
Thanks to all the commentators.
Again many thanks for the release of the notes on the Gas Density issue. As maths is not my first language is there anyway the calculations for the gas density could be avoided when planning each individual dive by assigning a nominal END for the He% e.g. a He% that gives you a END of 20M for every dive?
My dils have a PO2 of no more than 1.00 at max planned depth. I have three standard dils; 20/35 (40 metre), 15/55 (65 metre) and 10/70 (90 metre). The stand-alone Petrel displays the expected dil PO2 but even my enfeebled brain can calulate this on the basis of 20%, 15% or 10% O2...
