# Determine the total force and the absolute pressure on the bottom of a swimming pool

## 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.

## 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 .

## 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.

## 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.

## 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.

## 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.

## What are the correct units of pressure?

SI unit of pressure

For pressure, the SI system’s basic unit is Pascal (Pa), which is N/m² (Newton per square meter, while Newton is kgm/s²).

## How is force related to pressure?

When a force is exerted on an object it can change the object’s speed, direction of movement or shape. Pressure is a measure of how much force is acting upon an area. Pressure can be found using the equation pressure = force / area. Therefore, a force acting over a smaller area will create more pressure.
