Orifice
Sudden change
Calculation of the local pressure loss at a sudden change of the cross sectional areas (sudden expansion or sudden contraction) with sharp corners at turbulent flow regime for incompressible and single-phase fluid flow through arbitrary shaped cross sectional area (square, circular, etc.) considering a smooth surface. See more information.
Thick edged orifice
Calculation of pressure loss in thick edged orifices with sharp corners at overall flow regime for incompressible and single-phase fluid flow through an arbitrary shaped cross sectional area (square, circular, etc.) considering constant influence of surface roughness. See more information.
