Diving for 30 minutes at an Average Depth of 20 metres with Gas Used of 150 bar from a Cylinder Size of 12.2 litres your Surface Air Consumption (SAC) rate rounding up is: Disclaimer: This calculator provides information about gas use in scuba diving.or example, if we use 150 bar of gas from a cylinder with a water capacity size of 12.2 litres, at an average depth of 20 metres for a time at depth of 30 minutes, the SAC (lpm) is (((150 * 12.2) / ((20 / 10) + 1)) / 30) = 20.4 litres per minute.
