# Hydrostatic Pressure Equation

## Definition - What does Hydrostatic Pressure Equation mean?

Hydrostatic Pressure Equation is a process which states that the atmospheric pressure decreases with gradual increase in the height above the ground. It is mainly due of the force that is exerted by the air above the ground. When the net upward pressure is similar to the downward gravitational force there is hydrostatic balance. It is one of the most important concepts of meteorology that explain the interpret analysis and thickness charts easily. Hydrostatic pressure can be calculated by determining the volume of infinitely small cube of fluid.

## Petropedia explains Hydrostatic Pressure Equation

Hydrostatic pressure is determined by the weight of the fluid above the measurement point. The properties are not constant thus they depend on some factors such as local gravity and the density of the fluid. It plays a vital role to produce equilibrium. Moreover, it is also affected by the depth determined from the surface. The units in of the hydrostatic pressure are not always precise as the temperature of the fluid does not remain the same. However, the fluid level is independent of the density changes that occur due the fluctuations in the temperature.
