A nuclear submarine can stay and operate underwater for a couple decades, so long as it’s adequately stocked with enough supplies and ration for its onboard crew to survive that long. Obviously, that’s nowhere near the realm of possibility, so submarines must resurface to load fresh supplie...
@ Anon1369- I think it depends on the type of submarine you are getting on. I have a buddy who went to the navy and was stationed on a submarine. He said the quarters were very small, and they would stay under water for long periods of time. I would think this would require seriou...
How does a ship stay afloat on water?Density:In science, density is the ratio of the mass to the volume. For an object having irregular shape, we can solve its density by taking its mass by weighing and dividing by the local gravity. Then to measure its volume, we can submerge the ...
hunter-killer submarine. Unlike conventional submarines that India operates which need to surface to charge their batteries often - sometimes as frequently as 24 hours - INS Chakra can stay under as long as it wants. Its ability to stay underwater is restrained only by hu INS Chakra是俄国做,...
During World War II, submarines used this current to enter and leave the Mediterranean without even turning on their engines! Tidal Currents The gravitational pull of the moon usually creates two high tides and two low tides each day. HowStuffWorks Tidal currents, as their name suggests, ...
Humboldt squid are the smallest of the three, about 6 to 7 feet (1.8 to 2.1 meters) long and 100 pounds (45.3 kg). How do these marine animals get so big? The most common explanation is a phenomenon called deep-sea gigantism. The theory suggests that over time, small shallow-water ...
Some tunnels omit air entirely and instead use water. Water flows much like air, but it has greater density than air and is more visible, too. Those properties help scientists visualize flow patterns around submarines and ship hulls, or even better see shockwaves created by very fast aircraft...
These seafaris will take us far closer to marine wildlife than is currently possible. Clear submarines will offer whole viewing panel windows for tourists to be up close and personal with sharks, fishes and deep-sea animal divers. Hear the sights and sounds of underwater unlike ever before!
Can you briefly explain, if you can, the engineering behind how submarines are able to navigate such crushing depths in the first place—and why Titan was presumably unable to? The key is the design of the hull that protects the vessel against the large external water pressure th...
It looks like a giant ship sinking in the sea. It will be a permanent mobile exploration station for scientists to observe what is going on under the surface of the sea. According to him, half a dozen such vessels will be built and launched. Transcript: Look, can you guess what it is...
