Pascal's Principle
Pascal's principle states that the pressure exerted on a confined fluid is transmitted equally in all directions throughout the fluid, as long as the confining walls are strong enough to prevent deformation. This means that an increase in pressure applied to one part of a confined fluid will result in an equal increase in pressure throughout the entire fluid. The principle is named after Blaise Pascal, the French mathematician and physicist who first formulated it in the 17th century. It is a fundamental concept in fluid mechanics and has many practical applications, including in hydraulic systems, pumps, and actuators.
