Sagot :
Pascal's law or the 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.
The easiest way to give you Pascal's principle of transmission of fluid-pressure is to say that it was a principle in fluid-mechanics that stated that pressure exerted anywhere in a closed and confined incompressible fluid is transmitted equally and evenly in all directions throughout the fluid such that the pressure variations remain the same.
