Hydraulics

Hydraulics is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases.

Principles of hydraulics

Hydraulics derives from the Greek word ὑδραυλικός (hydraulikos) which in turn comes from ὕδωρ (hydor, Greek for water) and αὐλός (aulos, meaning pipe).

A fundamental feature of hydraulics is the ability to use leverage and Pascal's law to generate a large force over a large distance or leverage. The hydraulic lever, a simple machine, was used extensively in the construction of ancient structures like the Pyramids.

Applications of hydraulics

Hydraulics is used in many areas such as in the mechanical industry, the automotive industry, construction equipment, mining, materials handling, oil and gas, etc. Some examples include backhoes, dump trucks, hydraulic presses, and hydraulic cylinders.

Hydraulic circuits

A hydraulic circuit is a system comprising an interconnected set of discrete components that transport liquid. The purpose of this system may be to control where fluid flows (as in a network of tubes of coolant in a thermodynamic system) or to control fluid pressure (as in hydraulic amplifiers).
