How is pressure used in the control of a submarine's ability to dive?
Wiki User
∙ 10y ago
The process of a submarine to move from the surface of the ocean to a position underneath the surface is called a dive. This is accomplished by allowing water to fill the tanks of the submarine, the heavy water pressure now inside the vessel now will force it to sink below the surface, thus a "dive".

How many feet can a submarine dive?
A few submarines have gone to the bottom of the Pacific Ocean, 6 miles down, but, most can only dive to a few hundred feet. Any deeper and the pressure would crush their hulls. Diving to a few hundred feet is good enough for most military and civilian submarines. Also, how deep certain military submarines can dive is top secret information and is known only to a few people in the navy.
How far can submarines dive?
U.S. Submarines can dive 800-plus feet. (Official depth; however, can dive deeper. The US Navy itself acknowledges that most of it's attack submarines can operate down to at least 985 feet, and many to over 1400 feet.
How far can submarines dive underwater?
Straight to the bottom of the ocean.
What does a blue and white alpha flag mean?
A dive boat that is restricted in its ability to maneuver.
After a dive you are in a pressure group K what will your new pressure group be after a 34 minute dive?
Pressure group F.
How can submarines float and sink?
Submarines change their depth by use of ballast tanks. To dive, they open their tanks so that they become filled with water. They also angle their dive planes. To surface, they pump the water out of their tanks and fill them with pressurised air.
How does a submarine dive under water from the surface?
Submarines dive by opening vent valves that allow sea water to push air out of their ballast tanks.
To control my buoyancy as I ascend after a dive I should?
Gradually but continuously exhale. This is not only to control buoyancy, but to prevent damaging your lungs as the air in your lungs expands (due to external pressure decreasing, internal pressure increases)
What weapons did Japan bring to Pearl Harbor?
Kate Torpedo Airplanes, Val Dive Bombers, Zero Fighter Planes, Mini-Submarines launched from Mother Submarines.
How do you dive in faunasphere?
You have to have the special ability "Dive and Grab" to be able to dive. If you have the ability, go to water and search for bubbles. Once you find bubbles, scroll over them and see if they are red. If they are red, they are not ready yet. If they are green and have an arrow over them, they are ready for you to dive on them.
How deep can submarine dive in to the water?
it depends if the water is really deep or not and how good in shape the submarine isAns 2 - The operational depth of submarines is secret -(or 'classified' as navies say it) However it's generally accepted that most modern submarines can dive to around 1,500 feet and possibly even more in the case of the very latest. Submarines evolve and improve continually as no country wants anothers warships to be better.
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.
