Sorry these are stupid questions but i need some clarifcation about how gases work under pressure (been reading Cousteau). let me give a few examples:
1) let's say i'm 60 ft underwater and i'm breathing through a bamboo tube that goes vertically to an opening at the surface (a la James Bond). does that work? am i breating unpressurized gas while i'm under pressure? how would i understand the effects of that?
2) lets say in the same situation i'm breathing through a tube connected to an air compressor (like lobster divers in the third world, or like in Snuba). does some setting on the compressor have to relate to the depth of the hose? otherwise, won't you have a similar problem to #1? how does that work?
3) for skin diving (breath-hold), i assume you cannot get the bends -- can someone explain why that is?
thanks very much
