SAC Rate / RMV Calculator

Dive Info

Tank Info

Your RMV is:

cf/min

Sac Rate: psi/min
Total gas consumed: cf

Let's look at the math

Psi Used × (Tank Size ÷ Rated Pressure) = Gas Consumed
psi × cf ÷ psi = cf

(Average Depth ÷ 33) + 1 = Average ATA
( ft ÷ 33) + 1 = ATA

Psi Used ÷ Dive Time = Psi per Minute
psi ÷ min = psi/min

Psi per Minute ÷ Average ATA = Surface Air Consuption Rate
psi/min ÷ ATA = psi/min

Tank Size ÷ Rated Pressure = Tank Baseline
cf ÷ psi = cf/psi

SAC Rate × Tank Baseline = Respiratory Minute Volume
psi/min × cf/psi = cf/min
