Pascal's lawPascal's law(päskälz`) [for Blaise PascalPascal, Blaise, 1623–62, French scientist and religious philosopher. Studying under the direction of his father, a civil servant, Pascal showed great precocity, especially in mathematics and science. .....

Practical applications of the law are seen in hydraulic machines. Pascal's lawA law of physics which states that a confined fluid transmits externally applied pressure uniformly in all directions. More exactly, in a static fluid, force is transmitted at the velocity of sound throughout the fluid. The force acts normal to any surface. This natural phenomenon is the basis of the pneumatic fire, balloon, hydraulic jack, and related devices. See Hydrostatics Pascal’s Lawa law of hydrostatics that states that the pressure exerted by external forces on the surface of a fluid is transmitted by the fluid uniformly in all directions. The law was established by B. Pascal (published in 1663). Pascal’s law has great importance for engineering; for example, it is made use of in hydraulic presses.

Pascal's law - 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"
