# Pascal's Law

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Pascal's law states that the increase in pressure is uniformly applied in all directions in a confined fluid.

## Pascal's Law formula

$$\large{ \Delta p = \rho\; g\; h }$$
Symbol English Metric
$$\large{ \Delta p }$$ = pressure differential, hydrostatic pressure between two points $$\large{\frac{lbf}{in^2}}$$  $$\large{Pa}$$
$$\large{ \rho }$$  (Greek symbol rho) = density $$\large{\frac{lbm}{ft^3}}$$ $$\large{\frac{kg}{m^3}}$$
$$\large{ g }$$ = gravitational acceleration $$\large{\frac{ft}{sec^2}}$$ $$\large{\frac{m}{s^2}}$$
$$\large{ h }$$ = height of liquid column $$\large{ft}$$ $$\large{m}$$
