Submarine ballast tanks and their number depend entirely on the type of boat and its submerged displacement capacity. In general though, they're pretty big, on average about 6000 square feet or more.

What is a trim ballast tank?
That is a ballast tank used to alter the angle of the submarine up or down
What is the purpose of a submarine's ballast tank?
to keep the sub level or help it to dive and surface
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.
What changes take place in the ballast tanks when a submarine that has been under water rises to the surface?
The change that takes place in the ballast tank is the chief of the boat flips a switch and pumps the water out of them.
What is a submarines buoyancy?
A submarine has a variable buoyancy due to it's ballast tanks. When a submarine submerges, it fills it's ballast tanks with water which causes negative buoyancy. When a submarine surfaces, it pumps the water out of the ballast tanks thus giving it positive buoyancy.
What are the purpose of ballast tanks?
to control the buoyancy of a submarine
Where did they got the idea of making submarine.?
Theygot the idea from the fishes to build a submarine. As fishes have swim bladder they kept ballast tanks in the submarine.
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.
How does a submarine float?
It floats and sink by changing its buoyancy. The primary method of controling buoyancy is the ballast tanks. The air is let out of them and is displaced by water. This gives the submarine negative buoyancy, which will get the submarine to submerge. By blowing or pumping air into those ballast tanks, the submarine becomes buoyant and rises to the surface.

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?
If a sumbarine submerges what is it doing?
A submarine is a sea going vessel that is designed to run submerged or on the surface of the sea. Basically, by filling ballast tanks with sea water, the submarine will sink, and by blowing out the sea water from the ballast tanks with compressed air, the submarine will float on the surface.
