Pascal's law or principle of transmission of fluid-pressure is a principle in fluid mechanics that states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure variations (initial differences) remain the same. For example, when you inflate a balloon with air, it expands evenly in all directions.
In other words Pascal’s principle basically states that pressure applied to an enclosed fluid is transmitted undiminished to every part of the fluid, as well as the walls of the container.
In other words, if you have a fluid enclosed in a pipe (with no air bubbles) and change the pressure in the fluid at one end of the pipe, the pressure changes all throughout the pipe to match.
