There is a maximum depth at which a diver can breathe through asnorkel tube because as the depth increase, so does the pressuredifference, tending to collapse the diver's lungs. Since thesnorkel connects the air in the lungs to the atmosphere at thesurface, the pressure insid the lungs is atmospheric pressure. What is the external-internal pressure differnece when the diver's lungsare at a depth of 6.1m ? assume that the diver is in freshwater.
