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


Pascal's Law formula

\(\large{ \Delta p = \rho\;  g\;  h }\)   


 Units 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 \(\large{ft}\) \(\large{m}\)
