Question

How does pressure change as the depth below the surface of a fluid increases?

Answer 1

Answer:

The pressure increases linearly with the depth below the surface

Explanation:

The pressure at the bottom of a column of fluid is given by:

$p=p_0 + \rho gh$

where

$p_0$ is the atmospheric pressure

$\rho$ is the fluid's density

g is the gravitational acceleration

h is the depth below the surface of the fluid

As we see from the equation, the pressure is directly proportional to h, the depth below the fluid surface: therefore, as h increases, the pressure increases as well.
