How does buoyancy and density help a submarine to dive and float?

∙ 12y ago
A submarine has buoyancy tanks along its length. To dive or sink these are filled with water, which enters through valves, so the vessel becomes heavier. Its speed of descent can be controlled by the amount of water in the tanks and also by aerilons (small wings) which can be tilted to steepen the dive. There is obviously a depth limit for each submarine.
To surface the vessel blows the water out with compressed air, the vessel gets lighter (more buoyant) and rises to the surface.

Can a bowling ball float on water?
It depends on how the bowling ball is set. While it can float by being placing it directly on water by hands, it would not float if rolled/thrown inside. That could also depend on how much the ball weighs too.
What is the minimum surface interval required between a dive to 20 metres for 29 minutes followed by a dive to 14 metres for 39 minutes?
Q
What is the first color lost in the spectrum when descending in a dive?
Green
What is the opposite of free fall?
The antonym for free fall is upturn. Free fall also has several synonyms such as dive, plummet, plunge, drop, and collapse.
What is the highest dive into water in meters?
It is 58.28 metres by Rudolf Bok. But he suffered a fracture of the thoracic vertebrae and other internal injuries.
What will float then sink then float?
[I've heard this question asked as a kind of a twisted riddle, the answer to which is, "A drowning person": When a person is first in the water, they have air in their lungs and will float. As they drown, their lungs fill with water and they sink. Then, as their body decays and gases expand, the body floats to the surface -- LibertarianLaw]A submarine or a ship can float because the weight ofwater that it displaces is equal to the weight of the ship. This displacement of water creates an upward force called the buoyant force and acts opposite to gravity, which would pull the ship down. Unlike a ship, a submarine can control its buoyancy, thus allowing it to sink and surface at will.To control its buoyancy, the submarine has ballast tanks and auxiliary, or trim tanks, that can be alternately filled with water or air (see animation below). When the submarine is on the surface, the ballast tanks are filled with air and the submarine's overall density is less than that of the surrounding water. As the submarine dives, the ballast tanks are flooded with water and the air in the ballast tanks is vented from the submarine until its overall density is greater than the surrounding water and the submarine begins to sink (negative buoyancy). A supply of compressed air is maintained aboard the submarine in air flasks for life support and for use with the ballast tanks. In addition, the submarine has movable sets of short "wings" called hydroplanes on the stern (back) that help to control the angle of the dive. The hydroplanes are angled so that water moves over the stern, which forces the stern upward; therefore, the submarine is angled downward.
What happens to the buoyant force of a submerged submarine when water is taken into its tanks and it dives?
Unless the flooding and buoyancy was controlled, the submarine would continue to dive into the depths, possibly to be crushed by the great pressure of water.
How do I control my buoyancy as I ascend after a dive?
release air from your buoyancy vest.
Why can a submarine sink and float in sea water?
A submarine has "ballast tanks" which can be filled with water to make the vessel heavier (total density greater) than water and dive to required depth. These ballast tanks can also be filled with air (compressed air is kept on board for this) to make the vessel lighter and rise to the surface
How do submarines float with heavy metal?
They have ballast tanks that can be filled with air for buoyancy.Answer:Floating or sinking in water is related to the density of the entire enclosed volume of the submarine. Obviously if the metal in a submarine were compressed into a ball it would sink as its density would exceed the density of water. However the average density of a submarine (metal skin, interior equipment and air) is less than that of water and it floats. To dive the air in the ballast tanks is compressed or allowed to escape increasing the average density and it sinks. Replacing the air in the same tanks decreases the density and it floats once more.This is somewhat like a hot air balloon. The material in the balloon would not float in the air, however once the balloon is filled with hot air, the average density decreases and the balloon rises.
How do submarines and whales sink and float in water as needed?
Submarines and whales have ways to adjust their buoyancy. That's how they sink and float as needed. Each has a different method of adjusting buoyancy.The submarine controls buoyancy by adjusting ballast. Submarines have ballast tanks that can be filled with air or flooded down with water. When full of air, the ballast tanks provide enough buoyancy to keep the submarine afloat (provided the pressure hull is not full of water). The ballast tanks are open on the bottom, and have valves (called main vents) on the top. When we open the main vents, air is forced out by sea water that is coming in at the bottom. Once the ballast tanks are flooded, the boat will submerge. The crew then "fine tunes" the buoyancy by adding water to or pumping water out of tanks inside the pressure hull. These tanks are also used to trim the ship so it is neither heavy in the bow or the stern.Whales can fill their lungs with air to float or swim on or near the surface. When they dive, they take a breath and swim down against the upward force of buoyancy. As they move deeper, pressure forces their ribs (which are not rigidly attached to their vertebrae) inward and their lungs are compressed. This reduces buoyancy and makes it easier to go deeper. As far as actual "control" of their buoyancy, investigators are still not clear about many aspects of the workings of whale physiology, and debate and speculation continue.
How does the submarine's density compare to the water?
Submarines have variable density. When a submarine is in port, its overall density is less than that of water so some of it is above the surface of the water. They're made out of steel, which is more dense than water, but they're hollow; most of the volume of a submarine is air. To make a submarine able to dive, they pump water into tanks. By adjusting the amount of water, they can make the density equal to water's density, which allows the boat to stay at a certain depth without expending energy to hold it up.
What ship can go under water?
A submarine is a type of ship that is designed to operate underwater. It uses ballast tanks and a system of pumps to control its buoyancy and can dive and resurface using the principle of buoyancy.
Where do you find the submarine in sapphire?
you first go to steven to get dive and dive dvie
How deep can a naval submarine dive?
Classified.
How does a submarine dive and surface?
Massive ballast tanks can be filled with water or air, changing the weight and buoyancy of a sub. Once dived a sub can use hydroplanes to angle it towards the surface and use propulsion to drive to the surface.
Where is team aqua after you have found the submarine?
After you find the submarine you use dive up to the surface.
