2. Hydraulic fluid - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_fluid

   A hydraulic fluid or hydraulic liquid is the medium by which power is transferred in hydraulic machinery. Common hydraulic fluids are based on mineral oil or water. [ 1 ] Examples of equipment that might use hydraulic fluids are excavators and backhoes , hydraulic brakes , power steering systems, automatic transmissions , garbage trucks ...

3. Pipe network analysis - Wikipedia

   en.wikipedia.org/wiki/Pipe_network_analysis

   In fluid dynamics, pipe network analysis is the analysis of the fluid flow through a hydraulics network, containing several or many interconnected branches. The aim is to determine the flow rates and pressure drops in the individual sections of the network. This is a common problem in hydraulic design.

4. Tonne of oil equivalent - Wikipedia

   en.wikipedia.org/wiki/Tonne_of_oil_equivalent

   The tonne of oil equivalent (toe) is a unit of energy defined as the amount of energy released by burning one tonne of crude oil.It is approximately 42 gigajoules or 11.630 megawatt-hours, although as different crude oils have different calorific values, the exact value is defined by convention; several slightly different definitions exist.

5. Hydraulic analogy - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_analogy

   Hydraulic systems are deceptively simple: the phenomenon of pump cavitation is a known, complex problem that few people outside of the fluid power or irrigation industries would understand. For those who do, the hydraulic analogy is amusing, as no "cavitation" equivalent exists in electrical engineering.

6. Hydraulic machinery - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_machinery

   Hydraulic power pack; Transmission lines Hydraulic hoses; Passive components Hydraulic cylinders; For the hydraulic fluid to do work, it must flow to the actuator and/or motors, then return to a reservoir. The fluid is then filtered and re-pumped. The path taken by hydraulic fluid is called a hydraulic circuit of which there are several types.

7. Hydraulic conductivity - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_conductivity

   a table showing ranges of values of hydraulic conductivity and permeability for various geological materials. Values are for typical fresh groundwater conditions — using standard values of viscosity and specific gravity for water at 20 °C and 1 atm. See the similar table derived from the same source for intrinsic permeability values. [13]
