Question

State Pascal's law and verify it with the help of an experiment.

Answer 1

An increase in pressure at any point of a liquid at rest , is transmitted equally without any , in all the directions to every other point in the liquid . This is known as Pascal's Law. It was proposed by french scientist Blaise Pascal .

This law is useful in designing instruments like Bramah press ,Hydraulic press , Hydraulic jack etc. It is the principle in the development of hydraulic brakes , that are used in automobiles. It is also known as law of transmission of fluid pressure.

Answer 2

Pascal's law is a principle in fluid mechanics that states that pressure at a point, has infinite direction, and thus a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.
