Transmitting Pressure in a Fluid

    A.  Pascal’s Principle

        1.  When force is applied to a confined fluid, an increase in pressure is transmitted equally to all parts of the fluid.

    B.  Applying Pascal's Principle

        1.  A force pump causes a fluid to move from one place to another by increasing the pressure in the fluid.

        2.  Hydraulic systems take advantage of Pascal’s principle.

            a.  A hydraulic system multiplies a force by applying the force to a small surface area.

            b.  The increase in pressure is then transmitted to another part of a confined fluid, which pushes on a larger surface area.
