Figure 54  Common Gas 11 – Orifice Auto Size

This example models an Orifice where the size of the orifice diameter is unknown and the Pipe Flow Expert Software automatically calculates the diameter of the orifices based on the flow rate required.


Pipe Flow Expert supports Sharp Edged, Round Edged, Bevel Edged and Thick Edged orifices.


The software allows the user to enter additional data as appropriate to the type of orifice that is defined, such as rounding radius, bevel thickness, bevel angle, and plate thickness.


Orifices are widely used in piping systems to provide a regular and reproducible loss of pressure.  

Orifices are used to limit flow, to balance flow distributions in branching systems, and to measure flow.
