Question

Why does water pressure increase as the depth of the water increases?

Answer 1

It is due to hydrostatic pressure.

Explanation:

At sea level, airpressure is `14.5"psi"` (pounds per square inch), but we don't feel it because the fluids in our body apply the same force outward.

However, when we go down under water more pressure is felt. This is due to increase in hydrostatic pressure, the pressure exerted by water on us. The deeper we go under water, the greater the pressure of the water on us pushing us down. This is as pressure depends on depth of liquid (here water), its density and gravity and for every `33` feet the pressure increases by `14.5"psi"`.
