  2. Hydraulics - Wikipedia

    en.wikipedia.org/wiki/Hydraulics

    Hydraulics (from Ancient Greek ὕδωρ (húdōr) ' water ' and αὐλός (aulós) ' pipe ') [2] 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.

  3. Hydraulic engineering - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_engineering

    Hydraulic engineering as a sub-discipline of civil engineering is concerned with the flow and conveyance of fluids, principally water and sewage. One feature of these systems is the extensive use of gravity as the motive force to cause the movement of the fluids. This area of civil engineering is intimately related to the design of bridges ...

  4. Hydraulic machinery - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_machinery

    Hydraulic machinery. A simple open center hydraulic circuit. An excavator; main hydraulics: Boom cylinders, swing drive, cooler fan, and trackdrive. Fundamental features of using hydraulics compared to mechanics for force and torque increase/decrease in a transmission. Hydraulic machines use liquid fluid power to perform work.

  5. Hydraulic head - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_head

    Hydraulic head. Fluid flows from the tank at the top to the basin at the bottom under the pressure of the hydraulic head. Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum. [1][2] It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance (or bottom ...

  6. Hydraulic structure - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_structure

    Hydraulic structure. A hydraulic structure is a structure submerged or partially submerged in any body of water, which disrupts the natural flow of water. They can be used to divert, disrupt or completely stop the flow. An example of a hydraulic structure would be a dam, which slows the normal flow rate of the river in order to power turbines.

  7. Hydraulic pump - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_pump

    Hydraulic pump. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. They generate flow with enough power to overcome pressure induced by a load at the pump outlet.

  8. Hydrostatics - Wikipedia

    en.wikipedia.org/wiki/Hydrostatics

    Hydrostatics is a subcategory of fluid statics, which is the study of all fluids, both compressible or incompressible, at rest. Hydrostatics is fundamental to hydraulics, the engineering of equipment for storing, transporting and using fluids.

  9. Hydraulic cylinder - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_cylinder

    A hydraulic cylinder (also called a linear hydraulic motor) is a mechanical actuator that is used to give a unidirectional force through a unidirectional stroke. [1] It has many applications, notably in construction equipment ( engineering vehicles ), manufacturing machinery , elevators , and civil engineering.
