# Hydrostatic Pressure

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Hydrostatic pressure, abbreviated as HP, is the pressure a fluid exerts on an immersed object.

## Hydrostatic Pressure formula

$$\large{ HP = \rho\; g\; h }$$
Symbol English Metric
$$\large{ HP }$$ = hydrostatic pressure $$\large{\frac{lbf}{in^2}}$$ $$\large{Pa}$$
$$\large{ \rho }$$ (Greek symbol rho) = density of fluid $$\large{\frac{lbm}{ft^3}}$$ $$\large{\frac{kg}{m^3}}$$
$$\large{ g }$$ = gravitational acceleration $$\large{\frac{ft}{sec^2}}$$ $$\large{\frac{m}{s^2}}$$
$$\large{ h }$$ = height of fluid $$\large{ft}$$ $$\large{m}$$
