Flow versus Pressure

Flow versus Pressure

Flow versus Pressure

(OP)
What is the relationship of flow and pressure in a given pipe and orifice.  If you increase the pressure by 'x', what does the flow do?

RE: Flow versus Pressure

The flow increases by 'y'.  big smile

Seriously, there is a relationship for orifices and one for pipes.  Consult the Crane Technical paper No. 410.
    

RE: Flow versus Pressure

Even more seriously, what pressure are you talking about?  If you are talking about choked flow in a compressible fluid and raise the downstream pressure (but stay low enough to sustain choked flow) then absolutely nothing happens.

If you are talking about flowing a liquid and raise the overall pressure (not the differential pressure) then again nothing happens.

Ask your question again in a manner that will provide a basis for an answer that adds value.
