Here's a link to a thread I started awhile ago:
http://www.scubaboard.com/forums/basic-scuba-discussions/364228-air-consumption-rate-planners.html
I used my surface air consumption rate, and used the usual formulas to calculate my depth air consumption rate for different depths.
I listed my gas consumption in cu.ft./min. and in psi/min. there are tables for tanks that I use or my dive buddies might use.
Naturally, you can just do the math and figure out your gas consumption for any depth, but I figured a table would be helpful. Just for an at a glance idea, mainly to compare different tanks.
I used .7 as an average.
Anyway, they are attachments in my first post of the above linked thread.
Disclaimer: I was never suggesting in any way that anyone dive without a SPG, and I am not doing so now.
