# Determine the absolute pressure on the bottom of the swimming pool.

## How do I calculate the pressure at the bottom of my pool?

Pressure is the weight of the fluid mg divided by the area A supporting it (the area of the bottom of the container): P=mgA P = mg A .

## What is the total force on the bottom of a swimming pool?

Pressure = (1.2 x (1,000 x 9.8)) = 11,760Pa. (or N/m^2). Force on bottom = (11,760 x 78.55) = 923,748N.

## Does pressure increase or decrease when you go to the bottom of a pool?

If you dove to the bottom of a pool, why would you feel more pressure there than near the surface? Water pressure increases with the depth of the water. This is because the weight of the column of water above the object increases.

## What is the absolute pressure at a depth of 10m in a lake?

Total Pressure at the depth of 10 m. = Atmospheric Pressure + Pressure calculated. = 198 × 10³ Pa. Hence, the Pressure at the depth of 10 m is 198 kPa.

## Do you feel excess pressure while swimming underwater Why?

You can feel an increase of pressure on your eardrums. This is due to an increase in hydrostatic pressure, the force per unit area exerted by a liquid on an object. The deeper you go under the sea, the greater the pressure of the water pushing down on you.

## At what depth will water crush you?

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.

## Does pressure increase with height?

Atmospheric pressure decreases as the height of a surface above ground level increases. This is because, as the altitude increases: the number of air molecules decreases. … there is less air above a surface.

## How deep would you have to dive to experience an absolute pressure of 2 atm?

This means that at a depth of 33 feet deep in the ocean, there is a total pressure of 29.4 pounds per square inch (psi). This would be 2 ATMs of pressure. One ATM from the water, + one ATM from the water. We call this the ambient pressure or absolute pressure.

## How do you find absolute pressure underwater?

The total pressure, or absolute pressure, is thus the sum of gauge pressure and atmospheric pressure: Pabs = Pg + Patm where Pabs is absolute pressure, Pg is gauge pressure, and Patm is atmospheric pressure.
