The density of a fluid changes with temperature and pressure. It reduces with temperature and increases with pressure (Figure D 12) . The density-pressure function is determined by, among other things [...] things, the compressibility of the fluid. With β = compression coefficient ρ o = density at atmospheric pressure p a = atmospheric pressure

Reaction force generated if a fluid flow changes direction and/or velocity. The force F acts on the fluid from the outside as a supporting force. The force exercised by the flow on the environment is the [...] the flow force The force F acts on the fluid from the outside as a supporting force (reaction force). The force exercised by the flow on the environment is the flow force This Bernoulli force can be seen

is much greater than the diameter d. For Newtonian fluids, the flow rate through these kinds of flow resistors is mainly determined by the viscous fluid friction, geometry and pressure difference and may

property of hydraulic fluids , which plays a role in its selection and the usage limits of several devices ( Figure V 27 ). In order to compare the viscosity of different fluids, they must relate to a [...] Property of a fluid to act against resistance to the opposite laminar movements of two neighbouring layers (DIN 1342 and IDN 51 550). A distinction is made between dynamic viscosity and kinematic viscosity

Type of arrangement of electrical or fluid functional elements to achieve certain properties or functions.

Vertical height h in m of a column of fluid that, provided the density of the fluid is known, serves as a measure of the pressure that this column applies over the area of its base. The pressure head is

storage. Relevant norms: DIN 20 066 Hose lines in fluid technology DIN 20 078 Hose assemblies in fluid technology DIN 20 024 Hoses and hose line testing in fluid technology Safety rules for hydraulic hose lines [...] alongside transporting hydraulic fluid to moved consumers ( cylinders , motors ), often have the task of damping pulsations and pressure surges . As the hoses also have to work even under high pressures

group of fire resistant fluids of class HFD. In Germany chlorinated hydrocarbons are only used in closed hydraulic systems in coal mining due to their PCB content (HFDS fluids group). They cause problems

removed from the system in the form of heat. In fluid technology, these losses occur due to friction as a result of the viscosity of the pressure fluid, friction in the case of flow disturbances (vortices

eccentric mounting in relation to the rotor. External support requires internal fluid admission in the displacement chambers as fluid drawn is in. Application: vane pumps , valve-less radial piston pumps . Opposite:
