How do they get air in submarines?

Oxygen in submarines is produced by putting sea water through a process of electrolysis. Submarines typically have a couple of big oxygen tanks as well, used to quickly raise oxygen concentration if the system fails.

How is air supplied on a submarine?

Oxygen is supplied either from pressurized tanks, an oxygen generator (which can form oxygen from the electrolysis of water) or some sort of "oxygen canister" that releases oxygen by a very hot chemical reaction.

Where do submarines get air to surface?

To get a submarine to surface, the main vents in the top of the tank are closed and high-pressure compressed air is blown into the ballast tanks, forcing the water out through the flood ports at the bottom of the tank. Replacing ballast water with lighter air reduces the vessel's total mass.

Do submarines need to come up for air?

Modern subs don't need to come up for air, either. Chemical processes continually remove carbon dioxide from the air on board, while oxygen generators use electrolysis to extract oxygen from surrounding seawater. As long as the equipment is working properly, the air is always fresh and breathable.

How do submarines get compressed air?

It receives its supply of compressed air from the high-pressure system through the distributing manifold. addition to blowing the variable group of tanks, provides the compressed air for all the miscellaneous services aboard the submarine.

How Do Nuclear Submarines Make Oxygen?- Smarter Every Day 251

What happens to poop on a submarine?

Usually it sinks by itself, but some scrap metal can be added to aid its journey to the bottom of the ocean. Therefore, yes, submarines do produce trash that is thrown out into the ocean and it is terrible.

Do submarines make their own oxygen?

Oxygen in submarines is produced by putting sea water through a process of electrolysis. Submarines typically have a couple of big oxygen tanks as well, used to quickly raise oxygen concentration if the system fails.

Are submarines hot inside?

Even though the entire submarine has air cooling facility, only two decks are air-conditioned. The temperature in the rest of the submarine is around 30-35 degrees and the crew works in sweltering heat. The quality of the air is monitored constantly for impurities.

How long can a submarine go without refueling?

Nuclear power allowed submarines to run for about twenty years without needing to refuel. Food supplies became the only limit on a nuclear submarine's time at sea. Since then, similar technologies have been developed to power aircraft carriers.

Are females allowed to work on submarines?

The only officers with their own cabins are the captain, executive officer and weapon engineer officer. Only a small number of the 160-strong crew are female. For the officers on a submarine the wardroom is one of the few places — other than their cramped bunk — to relax.

How does a submarine engine get oxygen?

Most diesel submarines and modern nuclear submarines with auxiliary diesel engines use a snorkel to take in air for the engine and get rid of the diesel exhaust.

How long can US submarines stay underwater?

The limits on how long they can stay underwater are food and supplies. Submarines generally stock a 90-day supply of food, so they can spend three months underwater.

How is co2 removed from submarines?

In-order to remove CO₂ from the atmosphere, the submariners use a process called 'CO₂ Scrubbing'. This is done chemically using soda lime (sodium hydroxide and calcium hydroxide) in devices called 'scrubbers'.

How do submarines maintain pressure?

Now, a submarine is basically a metal container filled with air, and there is just enough air in a submarine to exert the atmospheric pressure at sea level. If the submarine goes underwater, the amount of air within it does not change (unless there is a leak, of course), so the pressure within the sub remains the same.

What is the longest a submarine has stayed submerged?

The longest submerged and unsupported patrol made public is 111 days (57,085 km 30,804 nautical miles) by HM Submarine Warspite (Cdr J. G. F.

How does the space station get oxygen?

Most of the station's oxygen will come from a process called "electrolysis," which uses electricity from the ISS solar panels to split water into hydrogen gas and oxygen gas.

Can you survive a tsunami in a submarine?

Some small and strong-hulled titanium submarines could survive stronger impacts and tsunami waves, but larger submarines with thinner hulls could be better adapted to long-term survival in a contaminated world.

Do you get seasick on a submarine?

Will I get seasick? Is it like being on a boat? Being on a submarine is very different to being on a boat. There is no rocking motion, as the submarine sits below the waves, and so people who get seasick on a boat will not do so on our submarine.

Are submariners exposed to radiation?

Background: Men stationed on nuclear-powered submarines are occupationally exposed to external ionizing radiation at very low levels and radiation dose for each individual is closely monitored.

Does it stink in a submarine?

You are probably wondering why I would call this post such thing... Since Submarines remain submerged with a sealed atmosphere they rely on a chemical called Amine to remove the carbon dioxide. This chemical makes everything stink.

Do submariners take bath?

The showers on a submarine are set up much like the ones in your home, well kind of. They have hot and cold water access with a recirculation pump so that the water stays hot so that you can use it quickly and efficiently by minimising water usage.

Do submariners bath?

Surrounded by water, the most precious commodity inside the submarine is water. “ None of us take a bath till we reach a port for replenishing,” explains a junior officer of the Indian Navy. Since water is precious, it is used only for drinking and cooking.

Why do submarines burn candles?

U.S. NAVY submarines burn sodium chlorate "candles" in an enclosed furnace for emergency and supplementary oxygen generation.

Why do submarines have curtains not doors?

A small curtain offers each submariner some privacy - vital when more than 20 men share this one room. Jamie says he has no problem with the six months they may spend at sea without daylight or fresh air, often with no access to communications with their families back at home.

Can oxygen be extracted from sea water?

“Electrolysis with seawater is a good method to tap oxygen and hydrogen. This is simple and conventional, with two power-connected electrodes placed in water. Oxygen and hydrogen gas bubbles would come out of the negative and positive ends respectively. The process can be performed with the support of solar energy.
