I'm not a diver but I am interested.
I'm working on a project and need info.
It concerns pressures in underwater caves.
ok say a cave is 20 feet down opens into a small area where there's air above, the air layer is right at the level of the water that goes into the cave, now if a person was in here exhaling for awhile or for sake of argument any extra air is added would the air above the diver keep compressing or would it break the barrier and rise up the exterior of the cave?
Would there be any compression of the air space?
Personally I'd think that the excess air/exhailing would freely rise up the outside of the cave but fluid mechanics is not my strong point.
