Why do submarines work?
Submarines have ballast tanks in them.........when it has to go deep down, the ballast tanks are filled with water, which increases its average density in regard to water(Relative Density).....and when it has to come up to the surface it empties the ballast tanks...and it rises. That's it.
What is a device used by submarines to control density?
Ballast tank
Which are the three type of crater repair methods?
Crushed stone, ballast rock, debris backfill
What is the population density of Stone Mills?
Stone Mills's population density is 10.7 people per square kilometer.
How do subramines float?
By altering the overall density of the ship by discharging the extra water they took on as ballast to make them sink
How does a submarine change its density?
To be able to submerge in the water, the sub has to become heavier. Ballast tanks are utilzed for this purpose. Water is let into them, and the sub sinks. To rise, air is pumped into the ballast tanks, and the sub rises.
What is the density of stone aggregate?
2.64
Why does a submarines density decrease when it pumps air out?
It doesn't pump air out; it forces water out of its ballast tanks to increase its buoyancy.
What are devices used by submarines to control density?
Allowing water into, or discharging it to replace by air, ballast-tanks built into the hull.
What is the ballast of a ship usually made of?
Ballast on smaller vessels is often water,high density materials like concrete or iron or just the weight of the crew. On larger vessels such as container ships,it is a combination of water and cargo.
What makes a lobster trap so heavy?
common traps have a cement or stone ballast located under the floor of the trap.
How do submarines control their density?
By their pumps and ballast-tanks: allowing water into the tanks to raise the vessel's density so can submerge, or pumping air into the tanks to displace the water and allow the submarine to surface.
