What is Pascal’s Law?
Pascal’s Law is:
It is known as the law of transmission of liquid pressure. It states as “When a pressure is applied any where on the surface to given mass of an enclosed liquid at rest, an equal uniform pressure is transmitted over the whole liquid. It gets transmitted through out the liquids and acts in a direction at right angles to the surface of the liquid everywhere.” Pascal’s Law, in term of the molecules means that the momentum transferred by them per unit time to a unit area is the same throughout the fluid. A recent application of Pascal’s Law in medical treatment is the water mattress (bed) used to cut down be-sore by distributing the weight of the body uniformly. Some of the important applications of Pascal’s Law are,
(1) Hydraulic press (or hydraulic lift).
(2) Hydraulic brakes.
(3) Hydraulic jack.
