Hydro dynamics
Hydro dynamics field cover both hydro-statics and hydro-kinetics as stated in DIN 13317. In this standard, dynamics covers both statics and kinetics as dynamics deals in general with forces and not only with the forces which are produce from kinetic energy.
Important note in fluid power technology
To have a good understanding of this post it’s require to mention that, the term “fluid” includes liquid, steam or gases, i.e. air are also a fluid when considered as a mixture of gases. In comparison with gases liquids are not as compressible.
In hydraulic field fluid power the laws of hydro –mechanics are use. Pressure or energy or a pressure control are transferred and applying the laws of hydro-statics and of hydro-kinetics.
Hydro-static is mechanics of still fluids and hydro-kinetics is mechanics of moving fluids.
Hydro-statics deals with the potential energy available when a liquid is enclosed and under pressure. This potential energy is call hydro-static energy. Hydro-static energy is apply in most of the hydraulic systems combine with kinetic energy. Furthermore, if the piston in the cylinder is move by a supply of flow under pressure, then not only is the pressure produce from effective potential energy, but a boost pressure is also effective which is create by the kinetic energy.
Kinetic energy
Kinetic energy is the energy of moving fluids. If a moving object meets and objects at rest, the moving object performs work on the body at rest.
Hydro-kinetics
As I mentioned hydro–kinetics is part of hydro dynamics field and in fluid power the laws of hydro-kinetics also apply and the effective forces that result.
Considering that the laws of hydro-static apply only to an ideal liquid – which is consider to be without mass and friction and incompressible – , hydro-kinetics may also be used to partially explain the type of losses occur in hydra-static.
