pressurized flow

Hydraulics is a branch of fluid mechanics specifically dealing with water as a major fluid in many engineering systems. It is safe to consider water as an incompressible fluid for typical engineering applications. Pressurized flow usually refers to the flow in closed conduits. Hydraulics of pressurized flow involves three basic equations: continuity, energy, and momentum equations. Head loss is important in hydraulics of pressurized flow regardless of system design or flow analysis. Darcy-Weisbach and Hazen and Williams equations typically estimate friction head loss. The friction factor depends on Reynolds number and relative roughness of the pipe. Total head loss includes friction head loss caused by fluid viscosity and local head losses at changes in the cross section, bends, and various pipe fittings. A pump provides energy head to, and a water turbine takes energy head from, the pipe system.

Closed-conduit flow may be defined as flow in completely filled conduits where no free water surface exists, or flow (relative motion) deep enough in a body of water that surface effects are not significant. Flow in pumping plant discharge lines and municipal water supply systems are examples of the first portion of the definition, and deeply submerged submarines may be examples of the second portion. In this paper only the case of completely filled pipelines and other closed conveyances will be considered. Also, the paper will be limited to flow with liquids such as water, and will apply only to incompressible flow.

As has been suggested, closed-conduit flow is in some respects very different from open-channel flow. For example, the fluid is completely constrained by the conduit walls and this constraint is manifested as a pressure force on the walls and within the fluid. No free water surface will normally exist and thus no hydraulic jump occurs.
Similarly, there will be no backwater curves and no significant changes in conveyance size and shape with changes in hydraulic gradient or rate of flow.

What about:

Een leiding met toevoer van een onder druk staande vloeistof.

I mean it says 'fed'.

'moving' is volgens mij pleonastisch.

I mean 'flow of moving' ??

flow implicits movement

So leave 'moving' out and you end up with:

A pipe through which a pressurized flow of a fluid is fed.

Je hebt een bron met vloeistof waar druk op wordt uitgeoefend en die dan - onder druk - door een leiding stroomt.


J.N.Adams [5] developed two mathematical equations which describes the pressurized flow of liquids in typical pipes within the realm of normal supply pressures.
