What is crush depth for a human?
Human bone crushes at about 11159 kg per square inch.
This means we’d have to dive to about 35.5 km depth before bone crushes.
This is three times as deep as the deepest point in our ocean..

How did ww2 submarines get air?
By making use of chemical reactions via heating Saltpeter, peroxides, or even liquid oxygen, WWII era submarines went thru a multitude of processes that stem from ancient techniques. The most notable technique that was incorporated in submarines was the air exchange system typically found on a snorkel.
Could China sink an aircraft carrier?
The Chinese report comes in response to U.S. dual-carrier training operations in the region using the USS Ronald Reagan and USS Nimitz. … The U.S. drills involve decided efforts to prepare for the possibility of a coordinated, multi-carrier attack.
Can a rogue wave sink an aircraft carrier?
Not much, carriers are large and heavy and designed to survive all kinds of nasties. As long as everything is secured and there is no way the water gets into the ship nothing should happen as long as it faces the wave. In other cases things might happen and it might, might topple.
Can a submarine communicate underwater?
U.S. Navy submarines use a specialized telephone system to communicate underwater. It works much like an AM radio, except that it transmits and receives sound waves instead of transmitting and receiving radio waves. Similar to land-based systems, underwater telephone systems use microphones and audio amplifiers.
Can a torpedo sink an aircraft carrier?
The new class of speedy torpedoes can’t be guided, but can fire straight toward US Navy carriers that have little chance of detecting them. Torpedoes don’t directly collide with a ship, but rather use an explosion to create an air bubble under the ship to bend or break the keel, sinking the ship.
Do submarines have showers?
Submarines have to distill water they need for drinking, cooking, and bathing from seawater and have a limited supply, so the crew takes “submarine showers” – turn the water on and wet down, turn the water off and soap up.
Can you swim to the Titanic?
An anniversary deep-sea diving expedition will offer tourists a chance to visit the R.M.S. Titanic, a hundred years after the legendary ship sank to the bottom of the frigid North Atlantic. … The trip to Titanic’s resting place takes about 2.5 hours, and a round-trip dive lasts about 8 to 10 hours.
How far can a torpedo go?
The torpedo operates at depths of 500m and is guided by active/passive homing system. The torpedo is propelled by an advanced pump jet engine and can engage targets within the range of over 40km, at a maximum speed of 40kt.
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.
Is a submarine faster than a ship?
A submarine can be faster than a boat. … Nuclear power allows submarines to go faster than surface ships. (This may be true.) The fastest submarine is claimed to be the Soviet K-162, launched in 1969, with a top speed of 44.7 knots (82.8 km/hr).
What does a submarine do underwater?
Unlike a ship, a submarine can control its buoyancy, thus allowing it to sink and surface at will. To control its buoyancy, the submarine has ballast tanks and auxiliary, or trim tanks, that can be alternately filled with water or air (see animation below).
Do submarines have WIFI?
Even when a submarine is on the surface, the crew’s access to the internet is severely restricted. … There would be NO allowed personal use of wi-fi or bluetooth within a submarine. The vessel MIGHT have a wired LAN for MWR, protected against signal leakage or intrusion.
Can a human survive 47 meters underwater?
According to the US Navy dive decompression tables a diver may spend up to five minutes at 160′ (47 meters) without needing to decompress during their ascent. The longer a diver stays underwater the greater their exposure to “the bends” becomes. … The bubbles can cause the bends.
Why are submarines so slow?
You can tell by that wake that it is not cutting through the water very cleanly. This is why modern submarines, with their hull form optimized for submerged operation, are slower on the surface. … The speed of a boat while going upstream= speed of boat in still water – speed of water current.
Is it possible to sink a US aircraft carrier?
Carriers are nearly impossible to sink. Because of their vast size, U.S. aircraft carriers have hundreds of water-tight compartments. … So that one weapon that might penetrate a layered defense isn’t likely to do great damage to the carrier.
Can you drink alcohol on Navy ships?
“The use or introduction for drinking purposes of alcoholic liquors on board any naval vessel, or within any navy yard or station, is strictly prohibited, and commanding officers will be held directly responsible for the enforcement of this order,” reads the hundred year-old order.
How fast can a submarine go underwater?
How Fast Can a Submarine Go? This is classified as well. However, U.S. nuclear-powered submarines can go faster than 23 miles per hour, which is 37 kilometers per hour or 20 knots (nautical miles per hour) underwater.
How deep can a ww2 submarine go?
World War II German U-boats generally had collapse depths in the range of 200 to 280 metres (660 to 920 feet). Modern nuclear attack submarines like the American Seawolf class are estimated to have a test depth of 490 m (1,600 ft), which would imply (see above) a collapse depth of 730 m (2,400 ft).
Can a human dive to the Titanic?
Luxury travel company Blue Marble Private will offer diving expeditions to the world-famous Titanic wreck site beginning in May 2018. For a mere $105,129 per person, tourists can explore the wreck off the coast of Newfoundland, Canada during an 8-day expedition. … A ticket on the one and only voyage cost $4,350.
