Fluid Power is the use of fluids under pressure to generate, control, and transmit power and is subdivided into:. Hydraulics using a liquid such as oil or water, and Pneumatics using a gas such as air or other gases.. Hydraulic principles make up parts of our everyday life, from monitoring the weather to moving heavy objects.
Fluid power advantages Fluid power is used in a diverse range of applications from mobile construction and aerospace equipment to powering industrial machinery, and offers several advantages over other types of motive force.
