Where is the highest air pressure in the atmosphere?

sea level
The depth (distance from top to bottom) of the atmosphere is greatest at sea level and decreases at higher altitudes. With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing altitude.

What PSI Can a human survive?

Originally Answered: What is the highest pressure a human can withstand? Using normal atmosphere, people can function at 2.5 times atmospheric pressure, or 2.5 bar. At 2,5 bar, a person inhales enough oxygen molecules to equal a lungful of pure oxygen at normal atmospheric pressure.

What is the highest psi on a pressure washer?

4600 PSI
Within Gas Pressure Washers, the highest PSI is 4600 PSI or Greater PSI. At the Home Depot, we consider up to 1899 PSI light duty for vehicles or outdoor furniture. Medium duty, which is recommended for fences or patios, is between 1900 – 2799 PSI.

How strong is kPa?

Kilopascal or kPa Definition 1 kPa is approximately the pressure exerted by a 10-g mass resting on a 1-cm2 area. 101.3 kPa = 1 atm. There are 1,000 pascals in 1 kilopascal. The pascal and thus the kilopascal are named for the French polymath Blaise Pascal.

How much PSI can break bones?

One cubic inch of bone can withstand the weight of five standard pickup trucks, give or take a few pounds. If you’re looking for the specifics to snap a piece of your skeleton, it takes about 4,000 newtons of force to break the typical human femur.

How much psi can skin take?

The body is a lot more resilient than you think. The human body can withstand 50 psi (pounds per square inch) and that’s if it’s a sudden impact. However if it’s sustained pressure, the body can withstand up to 400 psi if the weight is gradually increased.

Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides. The ocean’s pressure can indeed crush you.
