# Underwater Pressure

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

$$\large{ p_u = 1025 \; g\; d }$$
Symbol English Metric
$$\large{ p_u }$$ = underwater pressure $$\large{\frac{lbf}{in^2}}$$   $$\large{Pa}$$
$$\large{ g }$$ = gravitational acceleration $$\large{\frac{ft}{sec^2}}$$   $$\large{\frac{m}{s^2}}$$
$$\large{ d }$$ = depth under water $$\large{ft}$$  $$\large{m}$$
