What else can I help you with?
If you float face down in a pool what surface are you lying on?
You would be lying on the surface tension of the water, with the pressure of your body evenly distributed across the water. The surface tension allows you to float effortlessly.
What would the atmospheric pressure be at the bottom of the Marianas Trench if there were no water?
If there were no water at the bottom of the Marianas Trench, the atmospheric pressure would be approximately 101.3 kPa (kilopascals), which is the standard atmospheric pressure at sea level. The depth of the trench, about 10,994 meters, exerts an immense pressure due to the weight of the overlying water, but without the water, only the weight of the air would contribute to the pressure. Thus, the pressure would be comparable to what we experience on the surface of the Earth.
Where would you find the least amount of pressure?
The least amount of pressure can be found in a vacuum, which is a space devoid of matter. In such environments, like outer space, there are very few particles to exert pressure. Additionally, within a body of water, pressure decreases with depth, so the surface of a large body of water would also have lower pressure compared to deeper levels.
Why does water pressure increase with surface area and fluid density?
Water pressure increases with surface area because a larger surface area means the force is distributed over a greater area, resulting in higher pressure. Fluid density also affects water pressure because denser fluids have more mass per unit volume, increasing the pressure at a given depth due to the weight of the fluid above.
If you are submerged in a liquid denser than water what will happen to the pressure?
The pressure will get higher quicker than in water because there is a different density between the liquids, and because there is a higher density, the liquid will be heavier and would push on you more than the smaller density of water. if you would submerge deep in that liquid, you will explode at a lower distance from the surface than in water.
Is the force of the water on the piers the same at the water surface as it is 30m below the surface?
No, it would be less due to compression by weight of the surface area water. Every so many feet (meters) down, another "atmosphere" of pressure is exerted. Ergo, water at the seabed would exert more pressure on the pier than the water at the surface.
What would happen to a balloon full of air if you moved it from above a water surface to ten feet below the water surface?
The balloon would shrink in size as the pressure increases with depth, causing the air inside to compress. If the balloon were to reach a depth of ten feet below the water surface, it would likely shrink significantly due to the increased pressure underwater.

What is the pressure at the surface of water?
The pressure at the surface of water is equal to atmospheric pressure. On average, this is about 101.3 kilopascals or 14.7 pounds per square inch at sea level.
What do artesian wells use to bring water the surface?
Artesian wells rely on natural pressure within the underground aquifer to bring water to the surface without the need for pumping. This pressure is created by the weight of the overlying rock layers that confine the water in the aquifer. When a well is drilled into the confined aquifer, the pressure forces the water up through the well to the surface.
Would you expect the suction in the soil to be 0 at any time?
Soil suction is zero at the phreatic surface. This is the point where the pore water pressure is equal to the pore air pressure. Above this surface pore water pressure becomes increasingly negative compared to pore air pressure and as such matric suctions develop. Below the phreatic surface the pore water pressure becomes increasingly positive and the pore spaces are totally saturated.
How do you calculate the water pressure in psi?
To calculate water pressure in pounds per square inch (psi), you can use the formula: pressure force / area. This means that you divide the force exerted by the water on a surface by the area of that surface. The result will give you the water pressure in psi.
How often does it flood on mars?
There is no liquid water on the surface of Mars. The atmospheric pressure is so low and the temperatures are so cold that any water on the surface would freeze and boil at the same time.
What is water pressure in bar at 10 meters?
Water pressure increases by approximately 1 bar for every 10 meters of depth in freshwater. At a depth of 10 meters, the water pressure would be about 1 bar, in addition to the atmospheric pressure at the surface, which is roughly 1 bar as well. Therefore, the total pressure at 10 meters depth would be about 2 bars.
What point is water pressure greatest than the iceberg?
Water pressure is greatest at a depth of about 10 meters below the surface, where the pressure is equivalent to the weight of a column of water 10 meters tall. This pressure is greater than the pressure exerted on an iceberg floating at the surface, as the weight of the water column increases with depth.
Do you experience more pressure when you swim on the surface of water or under the surface?
Of course when you swim under the surface of the water. The lower you go in the water, the greater the pressure. That's why divers have gauges with them to determine their depth or to know how deep they are in the ocean.
