14.5: Pascal''s Principle and Hydraulics

Pascal''s Principle. Pascal''s principle (also known as Pascal''s law) states that when a change in pressure is applied to an enclosed fluid, it is transmitted undiminished to all portions of the fluid and to the walls of its container. In an enclosed fluid, since atoms of the fluid are free to move about, they transmit pressure to all parts of the fluid and to the walls of the container.
