how people get oxygen in aeroplanes/submarines for breathing?

Answer 1

Depends on the circumstances. Compressed tanks of some sort are always on planes above a certain altitude.

True, some commercial aircraft do compress outside air to provide breathing air for the cabin, but compressed air tank is a required backup, especially for crew. Passengers with hypoxia aren't terribly disagreeable. With a loss of cabin pressure on a commercial flight, those little masks drop down, with enough air for a short time.

General aviation almost always uses compressed air tanks, and requires crew to use supplemental air above 17,500 feet, and full oxygen masks above 25,000 feet. Memory is spotty, I always use oxygen above 7000 feet, and don the full mask at 15,000 feet. Good question. I have BFR coming up soon, but first I have to pass the medical.

Submarines do make some of their air, they also surface to take on fresh air, and they also have tanks.

Answer 2

hi mahesh , that's the qestion of my type , hey i think thatyou r from india,
hey , in aeroplanes the air allowed to enter by the the stuff covering made on the plane, but they also look after that the air may not enter in large amount ,

now in submarines the water it'self gives the oxygen to people in submarine , this is by the unique method that is known as Electrolysis of water , i think that you r not in doubt

Answer 3

Compressed liquid Oxygen cylinder in aeroplanes.
Oxygen is taken out from water

Answer 4

In Airplanes, all the pressurized air comes out of the compressor stage of the engine, this is called "bleed air".

Answer 5

airplanes just compress the outside air and bring it in.

submarines usually make oxygen from water (electrolysis and such works).

Answer 6

hi,they have oxygen cylinders

Answer 7

i guess there is an oxygen generator on it, both of them, i guess

Answer 8

i think some corner shops sell these products ,

Answer 9

They don't. They just hold their breath.
