What we breathe on the surface of the earth is a mixture of gases which consist of Oxygen with 21%, Nitrogen with 78%, and many more. When we breathe in, the entire mixture of air goes into our body and the body expels carbon dioxide using oxygen. All the other gases go out along with carbon dioxide. Those gases are not used by our body.
Oxygen is present everywhere
in the earth's atmosphere, so we take oxygen very easily. But have you
ever wondered how people breathe in submarines? Any submarine is completely
closed from all sides and remains in the depths of the sea for many days. Due
to which oxygen supply is not always available inside as like on the ground. Today
we tell you how people sitting in submarine take oxygen.
To create a breathable
environment in any submarine, two things are very important:
First:
The oxygen that has been used must
be replaced with new oxygen, as the reduced amount or unavailability of oxygen
will lead to the suffocation of those present in the submarine.
second:
Removing the carbon dioxide
produced by respiration from that environment, otherwise, that place will become
toxic and not breathable.
In that atmosphere of the
submarine, oxygen is supplied from a large tank of oxygen or from an oxygen
generator in which the water is converted into oxygen by electrolysis and sent
for supply throughout the submarine. The oxygen supply is connected to a
computer system that measures the concentration of oxygen in that atmosphere
and keeps the oxygen flowing throughout the submarine as needed.
The increasing carbon dioxide
concentration in that atmosphere is trapped with soda lime (sodium hydroxide,
calcium hydroxide) and prevented from returning to the atmosphere.
So in this way, the balanced
mixture of oxygen and carbon dioxide in the submarine makes the person breathe
easily present in that submarine.
