SAC formula

[The Natural]

Anyone have the SAC formula on hand? I'm bored at work and doing some math to pass the time.

In my dive book...LOL

I stole the formulas from this site though:

I used this formula and compared it to the formulas I had in my AOW class. The results where almost the same (give or take a cubic foot).

(((Pb-Pe)/Pb)x((Pb/Pw)xV)/T)/((D/33)+1)

Where:
Pb = Beginning Pressure
Pe = Ending Pressure
Pw = Working Pressure of Tank
V = Nominal Volume of Tank
T = Time of Dive in Minutes
D = Average depth of dive

if you are doing math, just to pass the time you could teach me how to do the mathmatical stuff so i can pass my physics test, i am so ignorant on this stuff

If you are killing time, derive it... it's pretty easy.
