How Are People Able to Breathe Inside a Submarine?
Inside submarines, oxygen is replenished, carbon dioxide is removed and exhaled moisture is eliminated to keep the air breathable. Oxygen

This makes the density of the submarine greater than the density of the water and the submarine sinks. Tanks of compressed air are kept on the submarine and when the crew wants to go back to the

How does ballast in a submarine work?
Submarines have used a system of compressing air in a chamber, and filling a chamber with outside water to change buoyancy. Early designs used a piston in a single chamber to compress

Why are high pressure air tanks used in submarine emergency blow
Chemicals cannot be compressed like air, and while air can be refilled while at sea, several ballast blows of chemical would need to be stored instead of just one set of ballast. At the end of the day, air is

Compressed air (submarines)
You need air lower in density than the surrounding atmosphere to get positive buoyancy (or a low density gas like Helium or Hydrogen). Compressing air makes it higher density, so not as

Breathing Beneath the Waves: The Art of Air Supply for Submarines
When a submarine dives, it is surrounded by water pressure that increases by about 1 atmosphere (1013 mbar) for every 10 meters (33 feet) of depth. At such extreme pressures, the air

Dear Sean, A submarine has flasks with compressed air located in spaces not used by other equipment, and often in free-flooding spaces near stem and stern. Taken from a design report

Diving and Surfacing
When the submarine surfaces, compressed air flows from the air flasks into the ballast tanks and the water is forced out of the submarine until its overall density is less than the surrounding water

Re: Query re compressed air on submarines
A Typ IXC uboat had air flasks aboard having a total capacity of 6200 liters (219 cu.ft.) at 2920 psi. This was sufficient air to blow all main ballast tanks, fuel ballast and bow and stern

How Do Submarines Get Air? Exploring Their Unique Air Supply
Firstly, submarines carry a significant amount of compressed air in tanks, which is used for both breathing as well as powering various systems such as the ballast tanks.

U boat question: This might sound like an obvious question but how
Air compressors (one diesel, one electric) were not used to blow the tanks, but rather to charge the air flasks before the next dive. Modern submarines often use a dedicated low-pressure blower to fully

The Fleet Type Submarine
Air can be compressed easily aboard a submarine, as it requires a relatively small plant and comparatively simple equipment. It can be stored at any convenient

ELI5: Submarines dive by allowing water to expel air from their tanks
They have compressed air tanks on board (and compressors to refill them when they''re at the surface) but these are generally for emergency use only. Subs have control surfaces similar to the wings on a

ELI5: How do deep sea submersibles take compressed air down to
The compressed breathable air within the actual submarine is pretty negotiable when you consider how much the entire vessel weighs. Also, the compressed air is carefully monitored and figured into the

Q & A; Diving and Surfacing
A. It is true that air is released from the ballast tanks and water is let into them through special valves to enable a submarine to dive, but the sub does not get air back to surface again.

CIBSE Case Study: Ventilation
Opening the emergency blow valve empties the compressed air bottles into the ballast tanks, forcing the water out and lifting the submarine to the surface. Compressed air can also be used if there is a leak

eli5: How do submarines work (buoyancy) ? : r/explainlikeimfive
The submarine can fill compressed air tanks while surfaced and then use that compressed gas later to purge the ballast tanks. Purging the ballast floats the sub, filling the ballast sinks it.
