The maximum number of feet that a safety net can be placed directly below the working surface is 30 feet. However, closer is better and the net should be closer if possible.
The pressure is greater at 20 m below the surface of the sea. Pressure increases with depth due to the weight of the water above. Each additional meter of depth adds more pressure, so the pressure will be higher at 20 m compared to 10 m below the surface.
Pressure increases the deeper you sink beneath the surface of the sea. So 20 metres below the surface has more pressure than 10 metres above the surface.
A column of air exerts atmospheric pressure on the air or surface below it. This pressure is caused by the weight of the air above pushing down on the lower air or surface.
At a depth of 500 m below the surface, the pressure would be approximately 5 atmospheres (1 atm for every 10 m of depth).
the pressure decreases the pressure increases
add 1 atm (atmosphere) for every 10 meters below the surface
Melting of a rock at temperatures below its melting point would not produce liquid rock below the surface. The other processes, such as increased temperature or pressure, would lead to the formation of liquid rock.
Pressure is greater at 20 m below the surface of the sea than at 10 m below due to the increase in water column above, causing an increase in hydrostatic pressure. The pressure at any point in a fluid is directly proportional to the depth of the fluid above that point.
At a depth of 3500 km below the surface, Earth's inferred pressure is estimated to be around 1.3 million times higher than atmospheric pressure at the surface. This extreme pressure is due to the weight of the overlying rock and the compression of material at such depths within the Earth.
it increases
No, the force of water on the piers is greater at 30m below the surface compared to the water surface due to the increased pressure at greater depths. The pressure in a fluid increases with depth, so the force exerted by the water on the piers will be higher at 30m below the surface compared to the water surface.
At the surface of the Earth, about 99% of the atmosphere's total mass is located below 32 km. This is where most of the atmospheric pressure is concentrated. Therefore, the greatest fraction of atmospheric pressure is present at the Earth's surface.
