Pascal's law Scientific  

/ pă-skălz′,pä-skälz′ /

1. The principle that external static pressure exerted on a fluid is distributed evenly throughout the fluid. Differences in static pressure within a fluid thus arise only from sources within the fluid (such as the fluid's own weight, as in the case of atmospheric pressure).

Named after Pascal

Example Sentences

He said it exploits Pascal’s law, which says pressures on fluid within a closed system are transmitted equally in all directions.

From Seattle Times

He points out that this action occurs in accordance with the law of the distribution of pressure in a fluid body, commonly known as Pascal's law of fluid pressures.

From Project Gutenberg

This operation is in accordance with Pascal's law and the law of the conservation of energy.

From Project Gutenberg

Suffice it to say here that this theory disregards the two basic mechanical principles of tone-production,—Pascal's law, and the law of the conservation of energy.

From Project Gutenberg

Pascal's law is stated as follows:—"Pressure exerted anywhere upon a mass of fluid is transmitted undiminished in all directions, and acts with equal force on all equal surfaces, and in a direction at right angles to those surfaces."
