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
