Many scientists lament that we are in an era of great discovery. Our footprints are everywhere on the earth, and there are our human footprints in the cold South Pole and North Pole, although the top of Mount Everest has been conquered by human beings; Even launched a space probe to visit the eight planets in the solar system. But there is a place on the earth where people seldom set foot, and it is also a mystery in other places. It is located in Mariana Basin, with an altitude of11034m.

Mariana Basin is the deepest place in Shanghai, with the depth exceeding 1 1 km. If the world's highest Mount Everest is laid, it is more than 2000 meters away from the surface! Mariana Trench makes people feel terrible about the pressure of seawater. We usually live at the bottom of the earth's atmosphere and are under atmospheric pressure. The standard atmospheric pressure is 1034 kg, and the area is equivalent to one square centimeter. The surface area of adult skin is about 2 square meters, so generally speaking, the pressure on our body is about 20 thousand kilograms, which is 20 tons.

The sea of ten thousand meters is a hellish existence, where it is cold and dark, and the pressure is great, so the sun can't shoot there. At present, the earth is the only planet inhabited by life, occupying 7 1% of the surface area and its depth is 1 1034 meters, that is to say, it is the only planet inhabited by life. At present, humans without tools can only dive less than 40 meters, and the pressure there is unbearable; With the help of professional tools, humans have been able to dive to a depth of 700 meters. It is dark here, and there are powerful unknown creatures. They are facing great danger. If humans reach the seabed of 65438+100000 meters, they may encounter powerful unknown creatures. If they attack humans, they will surely perish.

The unit of pressure is Pascal -Pa, and the unit of pressure is Newton, which is equal to the pressure divided by the load area. The formula for calculating liquid pressure is the liquid density multiplied by the liquid depth, and of course the pressure at standard atmospheric pressure.
