without my log book handy, Difference between start and finish pressure e.g. 170 bar, multiply by tank size (12l) gives me a volume of 2040 lt. Divided by total time (32 mins) = 64l/min, divide by av depth factor i.e. 15mt = 2.5 times gas consumption, therefore 55/2.5 = 25.5 l/min sac equivalent. Ignore the temp change causing press drop/rise as Stoney had same air and water temp. Av depth gained from computer.
Sound good too you?
