Flow in pipelines
= 1.2*v m . As of a certain flow speed, which depends on the pipe diameter and the viscosity, the fluid becomes heavily swirled (turbulent) and this results in a high energy loss. This flow should generally [...] depends on the Reynolds number . As the formation of a laminar flow requires a build-up distance of the fluid flow pattern l a = 0.03 d i · R e (for example 20 mm internal pipe diameter approx. 1.3 m) compared
Hydraulic accumulator
Accumulator which stores a fluid under pressure and is therefore able to release hydraulic energy. Pressurisation is mainly based on gas pressure (air, nitrogen, " hydropneumatic accumulator ") and, more [...] withdrawal of the volume. With hydropneumatic accumulators and spring accumulators by contrast, the fluid pressure decreases - due to the element applying the load expanding - as the spring characteristic
