PASCAL'S LAW

In the physical sciences, Pascal's law or Pascal's principle states that for all points at the same absolute height in a connected body of an incompressible fluid at rest, the fluid pressure is the same, even if additional pressure is applied on the fluid at some place. The difference of pressure due to a difference in elevation within a fluid column is given by: where, using SI units,

Noun
1. pressure applied anywhere to a body of fluid causes a force to be transmitted equally in all directions; the force acts at right angles to any surface in contact with the fluid; "the hydraulic press is an application of Pascal's law"
(synonym) Pascal's law of fluid pressures
(hypernym) law, law of nature
