K-FACTORs (MINOR LOSSES) – HOW WE CALCULATE THEM? – …

WebThe L e /D method simply increases the multiplying factor in Equation (1) (i.e. ƒL/D) by a length of straight pipe (i.e. Le) which would give rise to a pressure drop equivalent to the losses in the fittings, hence the name "equivalent length". The multiplying factor therefore becomes ƒ (L+Le)/D. WebThis article provides methods to calculate the K-value (Resistance Coefficient) for determining the pressure loss cause by changes in the area of a fluid flow path.
