Submarines can pump sea water into or out of ballast tanks, if they wish to change their weight (of course, anything that enters or leaves a submarine will also change its weight - people, supplies, weapons, etc. - but if you just want to change the weight, the easiest way is to pump water into the submarine).

How do fluids help ballast chambers on a submarine?
A submarine actually controls its weight by allowing water to enter or exit hollow chambers in its hull. These chambers are called ballast tanks. Ballast is anything carried in a ship to give stability. When water is allowed to flood into a submarine's ballast tanks, the weight of the submarine increases. When this increased weight exceeds the submarine's buoyancy, the submarine will sink. To allow the submarine to rise, air is pumped into the ballast tanks. The air forces out the water, reducing the weight of the submarine. The submarine then becomes lighter, buoyancy increases, and it floats to the surface. A submarine can also be made to "float" underwater at any depth by adjusting the amount of water weight in its ballast tanks.
The buoyancy force on a submarine submerged in the ocean equals what?
the weight of the water displaced by the submarine.
What is the Kursk submarine weight?
25,000 tonnes
The buoyancy force on a submarine submerged in the ocean equals?
the weight of the ocean water displaced by the submarine.
When a submarine pumps water out of its floatation tank its density decreases and it floats. Why does its density decrease?
To rise again, the submarine's weight must be decreased. Air is pumped into the ballast tanks to force the water out. The buoyant force acting on the submarine now exceeds the submarine's weight. With positive buoyancy, the submarine rises. The less weight an object has the more its density decreases. Hope that kinda helps?
When a submarine pumps water out of its inflation tanks its density decreases and floats.why does its density decrease?
It is not the matter of density. When inflation tank is filled with water then the weight of submarine is more than the weight of the displaced water. So submarine is in the sinking condition. As water is pumped out then weight of displaced water which is known as Buoyant force would be more than the weight of the submarine. So it would float.
What is a w and d on a submarine?
My guess would be Weight and Draft
Did the submarine help change lives during the renaissance?
No
Why did they change the name u-boat to submarine?
the U boat 'is' the German word for submarine. western nations just used submarine. U boat is short for Unterwasserboot, which translates as undersea boat or under water boat or submarine.
If the upthrust is greater than the weight what happens to the submarine?
Well, if the Upthrust were greater than the weight, there would be a net force upwards, and as a consequence of newtons second law a=F/m it accelerates upwards. Hence, the submarine floats.
