Pressure is the force per unit area exerted on a surface, divided by
the area of that surface.
Pressure = Force/Surface Area
Therefore hydraulic pressure is the force per unit area exerted by a
fluid on the surface within the container.
For the demonstration of this relationship, is interactive animation on the left is simple yet effective. Buttons on screen provide the instructor with control over the force applied whilst pressure and force
are clearly indicated numerically and through use of colour.
The animation is part of our instructor pack for basic hydraulic principles, available for use in schools and colleges and includes interactive material to provide tutorials on all of the following:
