I know that Earth has a surface pressure of 101.325 kilopascals. So right now we are all under this pressure, but what types of pressures will we start to die at? high and low pressures in pascals please. Thanks.
The highest pressure a human can survive in is approximately 1,100 times atmospheric pressure, which is equivalent to about 16,000 feet (4,877 meters) below sea level. This pressure is typically found in deep-sea diving environments.
Humans cannot survive in the vacuum of outer space. The lack of atmospheric pressure would cause the body fluids to boil and the lungs to rupture. However, with proper protective gear and a pressurized environment, humans can survive in space.
At high pressures, the gases in the body (such as nitrogen and oxygen) can become compressed and cause a condition called nitrogen narcosis. This can lead to confusion, dizziness, and even loss of consciousness. Additionally, high pressures can also cause damage to the eardrums and other tissues in the body.
The Mariana Trench is the deepest point in the ocean, with pressures reaching over 1,000 times atmospheric pressure. It is highly unlikely that a human could survive in these extreme conditions without specialized equipment. However, some deep-sea creatures have adapted to survive in these high pressure environments.
Submarines are designed with thick, strong hulls that can withstand the high pressures of deep-sea environments. They also have systems in place to regulate the internal pressure to match the external pressure, preventing the hull from collapsing. Additionally, the air inside the submarine is continuously circulated and filtered to remove excess carbon dioxide and replenish oxygen levels.
