You're 100ft deep in a 12l tank, you're OOA and your buddy is nowhere to be found. You start a CESA, exhaling slowly and breathing the air your tank gives you as the pressure lowers.
It the following correct?:
- At 100ft an OOA 12l tank contains 46 liters of air.
- Every 33ft you go up, it gives you 12l of air.
- With deep breaths, taking into account you have to be careful with overexpansion, you'd get about 4l in each inspiration.
- So, you have about nine deep breaths to go up the 100ft to surface. (which looks like the perfect argument to explain someone that even in OOA there's no hurry to sprint up and die on the boat).
[Edit: No, it is not correct at all. As pointed by ErikH, you only get those 36l of air when you don't need them anymore. On the surface. At 66ft you do get 12l but you breathe them as 4l.
And, if you take some air in the path to 66ft it's even more "expensive".
In all, maybe there is reason to try to hurry a bit to the surface. An OOA at 100ft might not be the best moment to take pictures and practice your SMB deployment.]
