Hi Guys,
Just trying to get my head around the way pressure effects our air consumption and thought i would make sure i am grasping this correctly..
With my normal tank. If as an average, i go through the tank on the surface (0 feet/metres) in 60 minutes, does that mean when i descend to 10 metres where the pressure is 2 ata, i will consume my air on average, 2x faster - so if i could somehow start a dive at 10 metres, i would have a bottom time of 30 minutes?
Then at 50 metres or 6 ata my air would last 10 minutes - again not factoring the ascent descent?
If this is right, i do understand that i need to factor in time for ascending and descending as well as safety or deco obligations, but i just wanted to make sure i am well aware of the maths to do with pressure and air consumption.
Thanks,
Toefa
