    The endurance of the cylinder can be calculated from the volume, pressure and breathing rate of the user. The formula: volume (in liters) × pressure (in bars) / 40 (litres per minute) - 10 minutes (the 10 minutes is a safety margin, or reserve), so a 6-liter cylinder, of 300 bar, is 6 × 300 / 40 - 10 = 35 minutes working duration.

    A diver with a RMV of 40 L/min at 50 msw (6 bar) for 10 minutes will consume 40 × 6 × 10 = 2400 litres of free air – the full capacity of a 12-litre 200 bar cylinder. Imperial examples: A diver with a SAC of 0.5 cfm (cubic feet per minute) at 100 fsw (4 ata) will consume 0.5 × 4 × 1 = 2 cfm surface equivalent.
