If Challenger Deep is the deepest part of the ocean, it must therefore have the most water pressure at the depth.
a) How much pressure is down there ?.
b) How much pressure does it take to crush a human skull ?.
c) How far past design depth can a nuclear class submarine go before imploding ?.
d) Why dont researchers go more frequently to the ocean bottom, as in the challenger craft, for research ?.

a) About 1000 times atmospheric pressure.
b) I don't know, but probably less that 1000 atmospheres.
c) That is classified information, but military nuclear submarines can not go nearly deep enough to reach the bottom of the deep ocean.
d) Researchers do go to the very bottom of the deep ocean quite often, but they use special battery powered research submarines that can go way deeper than military nuclear submarines, but only for a few hours at a time because of the limited power provided by the batteries. I see them all the time on PBS programs about diving to the Titanic and mid ocean ridges and the like.

About every 33 feet of water increases the pressure by 1 atmosphere.
A nuclear submarine probably can only go about 500 ft deeper than it's "design depth". The actual design depth is the point when the ship explodes. The reported design depth decreases the max depth by some amount so that the crew of the sub does not accidentally take the ship to the point where it would explode.
Researchers do not go all the way down because of the technical and health problems associated with the pressure at that depth.

The Challenger Deep is the deepest known point in the oceans, 10,911 meters (35,797 feet) deep at its maximum
a. Approximately 30' = 1 atmosphere - 14.7 psi
b.
c. Classified but probably deeper than you'd expect. WW2 submarines had a crush depth of about 800-900'
d. Technology and cost. A Japanese robotic deep-sea probe, known as Kaiko, broke the depth record for unmanned probes when it reached the bottom of the Challenger Deep on 24 March 1995. Created by the Japan Marine Science and Technology Center (JAMSTEC), it was one of the rare few unmanned deep-sea probes in operation that could dive deeper than about 6,000 meters (19,680 feet). Its recorded depth of 10,911 m (35,797 ft) for the Challenger Deep is believed to be the most accurate measurement taken yet. Unfortunately, Kaiko was lost at sea on 29 March 2003, after just more than 8 years of service, when one of the secondary cables snapped during an approaching typhoon. Currently no other operational vehicle exists that is capable of reaching the same depths, and no other manned vehicle has come to the same depth as Trieste.

i'm no longer an authority at fluids whilst a fluid is at relax. the only tension it studies is one perpendicular to its floor. tension = weight of fluid above a disk with area A. For a fluid at relax with uniform density in sealed container P the strain is given by utilising the formulation P = p*g*y the place little p = density, g = gravity, y = intensity of fluid. because of the fact the freshwater is uncovered to a minimum of one greater fluid (air) The tension may well be chanced on by utilising the equation P = p*g*y + P environment. on account which you in all likelihood will use kilograms and meters you're able to desire to apply Pascals because of the fact the strain. one million environment = 101325 Pascals 4.one million atmospheres * 101324 Pascals/environment = 415432.5 Pascals ok so plug in the values the density of water is 1000 kg/m^3 415432.5 Pascals = 1000 kg/m^3 * 9.8 m/s^2 * intensity. + 101325 Pascals. 314107.5 Pascals = 1000 kg/m^3 * 9.8 m/s^2 * intensity clean up for intensity i think of it is nice yet i'm no longer a hundred% specific.

I'll answer part b) since nobody has correctly yet.
your body cannot be "crushed" by pressure in a fluid.
Your ear canal can burst if it is not properly equalized, Otherwise, being crushed by fluid pressure is a physical impossibility.
As an experiment, you can hold an egg in your hand and squeeze EVENLY from all sides. Fluids exhert pressure from all directions evenly, in this same way.

i can't answer you because it gave me alot of pressure understanding the question....and by the way i dont have the faintest clue.
