The Kracken:So it follows that an 80 CF tank @ 3000 psi = .027 cf per psi
Therefore if I use up 100 psi in 5 minutes then my SAC =
(100/5)x .027 psi or 20 psi/min x .027 which equals a SAC of .54?
If you used 100psi in 5min at the surface, yes. If you used 100psi in 5min at 33ft, then you'd divide by 2 (since your 100psi at 2 ATA is equal to 50psi at surface), etc.
