# Underwater Pressure

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Underwater pressure, abbreviated as $$p_u$$, is the added pressure exerted underwater directly above a spot at the water level.

## Underwater Pressure formula

 $$\large{ p_u = 1025 \; g\; d }$$

Where:

$$\large{ p_u }$$ = underwater pressure

$$\large{ g }$$ = gravitational acceleration

$$\large{ d }$$ = depth under water
