Medical Definition of Bernoulli's principle. : a principle in hydrodynamics: the pressure in a stream of fluid is reduced as the speed of flow is increased.
Pascal's law (also Pascal's principle[1][2][3] or the principle of transmission of fluid-pressure) is a principle in fluid mechanics that states that a pressure change occurring anywhere in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.[4] The law was established by French ...
