Hydrostatics Definition and Laws
Hydrostatics Definition
The Branch of science which deals with the study of fluids at rest.
Pascal’s Law
It states that the pressure or intensity of pressure at a point in a fluid at rest is equal in all directions.
Let consider a fluid at rest in a closed container then a change in pressure at one point will be transmitted without loss to every point of the fluid and to the walls of the container.
