Trying to figure out my SAC rate

[gcbryan]

To SteveTW, i find it interesting that a OW diver would be thinking about SAC. Excellent. I think i was diving 15 years before i was thinking of SAC and now i use it to plan dives. Slouth above gave an interesting web page to calculate SAC (thanks Slouth). I dive in metric-land these days and have forgotten all about psi but i leanred to do it this way:

- Dive to 10 meters (33 feet) which is 2 bar.
- Dive relaxed and breath down 10 bars on the gauge
- use a 12 cf tank with 200 bars air (about 2900 psi) 2400 cf of air
- calculate the usage and divide by 2 bars

Seemed easy for me to do. Came up to 11 cf/minute

I don't think you mean CF (cubic feet).

You are right. I did not mean to type "cubic feet" but liters per minute. Thanks for pointing out.
