Hello everyone,
The partial pressure of the atmosphere 33 feat benath the surface is doubled the normal amount. (2x760 mmHg). I can understand how lower you go down higher the pressure but I don't understand how you can measure atmospheric pressure under the sea. I mean under the sea you got water around you not atmosphere. Are the gases in atmosphere dissolved in this water. My question is mainly related to divers under the sea. They get double the atmospheric pressure of nitrogen and nitrogen narcosis could occur. So how do you get double the N2 in the atmosphere when you are surrounded by the sea. Also why do these effects occur when divers are using an oxygen tank. The gases inside the oxygen tank is normal atmospheric pressure right. Thanks
