Fluid power is a term that describes hydraulic and pneumatic technologies which use fluid to transmit power from one location to another. Fluid powers are used largely in many of the industrial branches. Hydraulics and pneumatics have infinite application in all sectors. Hydraulics relates to fluids and Pneumatics to gas. Pneumatics hold many advantages that make it more suitable for many applications.
Hydrostatics deals with the mechanics of still fluids and uses the theory of equilibrium conditions in the fluid. Actuators are mechanical or electro-mechanical devices that are responsible for moving or controlling a mechanism or system.
This course is designed in such a way that it gives a detailed note about hydraulics, pneumatics, and actuators.
After completion of this course, students will have a clear idea on the principles of hydraulics, hydrostatic, and pneumatics, and about their types in detail.
