Thank you for making this it was very interesting how they used compressed air to sink and float. I wonder what it would be like to work on one. Jun 22, John from England Apr 8, I do not like submarines and this website is dumb. Wonderopolis Apr 8, Wonderopolis Feb 24, Charlie Jun 12, This article was a very clear explanation for how a submarine works and I liked how they explained how buoyant force works.
I never knew it was so complicated. But I have one question, how does the captain control the submarine with his crew? Wonderopolis Jun 12, Nathan Mar 18, It seems like a cool experience going on a sub. Wonderopolis Mar 18, Who goes down there? Besides the one who drives it. Wonderopolis Mar 15, I think I would be scared to because I'm very scared of a submarine. Don't you? Wonderopolis Mar 12, Michael Mar 11, I would be soooooooooooooooo scared if I was on a submarine.
Being under the water gives me the chills. I always thought it would fill up with water. Now I know it won't. Wonderopolis Mar 11, Reico from Mrs. Bahler's Class Mar 11, Bahelr's Clas Mar 11, Asia from Mrs. I wonder why it is so bright when the people look out the window of the sub while they are underwater.

Water is also forced between the bow and stern trim tanks to keep the sub level. The submarine can steer in the water by using the tail rudder to turn starboard right or port left and the hydroplanes to control the fore-aft angle of the submarine.
In addition, some submarines are equipped with a retractable secondary propulsion motor that can swivel degrees. When the submarine surfaces, compressed air flows from the air flasks into the ballast tanks and the water is forced out of the submarine until its overall density is less than the surrounding water positive buoyancy and the submarine rises. The hydroplanes are angled so that water moves up over the stern, which forces the stern downward; therefore, the submarine is angled upward.

Science Channel, YouTube Some submarines use two hulls—one inside of another—instead of ballast tanks.
As the outer hull fills with water, the submarine dives. Submarines may carry nuclear fuel for up to 30 years of operation. When the ballast tanks are filled with air, the submarine rises to the surface because it has positive buoyancy.
With water inside the tanks , the sub has negative buoyancy so it sinks deeper into the ocean. Why do ships take on ballast water?
To provide adequate stability to vessels at sea, ballast weighs the ship down and lowers its centre of gravity. These ballast tanks are connected to pumps that pump water in or out.
Crews fill these tanks to add weight to the ship and improve its stability when it isn't carrying cargo. How do submarines get air? Oxygen is supplied either from pressurized tanks, an oxygen generator which can form oxygen from the electrolysis of water or some sort of "oxygen canister" that releases oxygen by a very hot chemical reaction. The carbon dioxide is trapped in the soda lime by a chemical reaction and removed from the air.
How deep can US submarines go? As a result, the submarines are capable of diving to depths of up to two thousand feet, and crush depth estimates run from 2, to 3, feet. At feet, Seawolf subs were designed to be slightly shorter than their predecessors, by just seven feet, but with a twenty percent wider beam, making them forty feet wide.
Can I buy a submarine? Several businesses in the United States and Europe cater to the recreational submariner. Why do submarines need to surface?
