## Hydrocyclone Filter Calculation Parameters

The ratio of the lower (d н) and upper (d в) drain pipe diameters is one of the most important parameters in the hydrocyclone calculations.The d в /d н ratio defines the condensed and clarified product ratio at the port outlet. Numerically, this relation can be represented by an approximate formula: Q н /Q в = 1.13·(d н /d в)³. Where: Q н – condensed product flow in the lower ...
