Water is used for a variety of purposes on a submarine, the most common being for depth control (Main and Trim ballast). Main Ballast Tank water is expelled by pressurizing the tanks with either hi-pressure air (emergency blow) or low pressure air from a device known as a Low Pressure Blower. Hi-pressure air is dumped into the tanks during critical casualties when the boat needs to get to the surface quickly; the Blower is used when the boat is at Periscope Depth and can take its time to force the water out. The boat needs to be at PD to use the blower - it has to be able to bring in outside air through the snorkel mast.
Trim ballast is brought in and expelled using mechanical pumps. Like all boats, there is more than one pump in case one fails.
For unwanted water (flooding, bilge water, etc.) another pump is used to pump the water overboard.
Sanitary water - waste water from showers, heads, galley, etc., is forced overboard using hi-pressure air. It's also one of the reasons I don't eat fish.
What else can I help you with?
How does water pressure affect a submarine?
When a submarine goes farther down in the water, the water pressure becomes greater. If the submarine goes to far, pipes can explode and let in water, or it can implode the submarine
Can water exert pressure on a submarine?
Yes, water exerts pressure on the hull of the submarine.
A sentence with submarine in it?
A submarine is only used under water.
How does water enter the submarine?
Water enters the submarine by letting water out not into its ballast tanks it enters from the flagura to the magura.
The buoyancy force on a submarine submerged in the ocean equals what?
The buoyancy force on a submerged submarine equals the weight of the water displaced by the submarine. This force acts in the opposite direction to the gravitational force, allowing the submarine to float or sink in the water.
How does water enter a submarine?
Water enters the submarine by entering through the butthole and leaving from the propellers
What does a submarine alter to rise and fall in water?
A submarine alters its buoyancy to rise and fall in water by adjusting the amount of water in its ballast tanks. When the tanks are filled with water, the submarine becomes heavier and sinks; when air is pumped into the tanks, the submarine becomes lighter and rises. This process allows the submarine to control its depth in the water column effectively.
How do submarines float and sink in water?
a submarine has a water tank. when the tank is filled then submarine sink in the water. and when the tank is empty then submarine float in water. use the formula density= mass / volume as mass increases(when the tank is full of water), the density of the submarine increases and it submerge into the water and vice versa.
Why does a submarine can sink and float in water?
A submarine can sink and float in water because it has ballast tanks that can be filled with water to make it sink and with air to make it float. By adjusting the amount of water and air in the ballast tanks, the submarine can control its buoyancy and stay submerged at a desired depth or rise back to the surface.
When water fills a submarine's flotation tanks the overall density of the submarine will...?
The density will rise and submerge the submarine.
What word starting with sub means a vessel that can go under water?
The vessel is a submarine.
How is the word submarine used in a simple sentence?
The submarine is under water.
