The average exchange of air per breath is 500 ml for men and 390 mL for women and the average breathing rate is about 12 times per minute.That's about 6 litres a minute, 0.360 m3/hr for men and 4 litres a minute, 0.240 m3/hr for women.he average exchange of air per breath is 500 ml for men and 390 mL for women and the average breathing rate is about 12 times per minute.
The average divers consumes about 24 or 25 litres of air a minute whilst on the surface. The theory behind this is that the average adult lung size is about 6 litres, but when relaxed we only breathe about 25% of this i.e., 1.5 litres.If we breathe about 16 times a minute that equates to (16 x 1.5) 24 litres a minute.e has a SAC rate of 25 litres per minute. 1  Work out how much air is available-Remove and ignore 50 BAR from the cylinder calculations. 2  At 25m (3.5 BAR) his breathing rate will be 3.5 (BAR) x 25 (SAC) = 87.5 litres per minute. 3  How many 87.5 (litres per minute) will go into 2040 (his available air) = 23 Minutes.
