O2 consumption _is_ depth dependent. To achieve a ppO2 of 1.3 on 70m in a XL "bladder" from a 10/50 Dil consumes more O2 than achieving ppO2 of 1.3 in a Air Dil at 30m. The O2 metabolism will just be proportional to the workload, but to calculate the O2 metabolism from the used O2 volume we would need a counter-lung+loop+scrubber+head estimate. //Anton -- Anton Lundin +46702-161604 _______________________________________________ subsurface mailing list [email protected] http://lists.hohndel.org/cgi-bin/mailman/listinfo/subsurface
