The same depth change of 1 m upwards will increase the gas volume in the BC to 1.3/1.2 × 2.78 = 3.012 litres, a difference of 0.232 litres. Example 2: The same diver as in example 1 at 30 m depth at the beginning of the dive with 200 bar in the 12 litre cylinder has about 3.1 kg gas in the cylinder, requiring about 3.1 litres of gas in the BC ...
