Pascal's law - Wikipedia
网页Pascal's law (also Pascal's principle [1] [2] [3] or the principle of transmission of fluid-pressure) is a principle in fluid mechanics given by Blaise Pascal that states that a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere. [4]

网页2024年8月9日 · Pascal’s principle, in fluid (gas or liquid) mechanics, statement that, in a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container. The principle was first enunciated by the French scientist Blaise Pascal.
Pascal’s Law - Explanation, Derivation, Applications, FAQs
网页What is Pascal’s Law? According to Pascal’s Law, “The external static pressure applied on a confined liquid is distributed or transmitted evenly throughout the liquid in all directions”. The static pressure acts at right angles to any surface in contact with the fluid.
Pascal’s Law: Statement, Formula, Examples, & Application
网页2023年4月6日 · Pascal’s law, or Pascal’s principle, states that a pressure change in one part is transmitted without loss to every portion of the fluid and the container walls. Since the pressure is transmitted undiminished, Pascal’s law implies that the total fluid pressure is the sum of the pressures from different sources.

网页2022年9月12日 · Pascal’s principle (also known as Pascal’s law) states that when a change in pressure is applied to an enclosed fluid, it is transmitted undiminished to all portions of the fluid and to the walls of its container. In an enclosed fluid, since atoms of the fluid are free to move about, they transmit pressure to all parts of the fluid and to ...
