WebThe minor loss coefficient measures a fluid’s energy loss in a pipe due to the presence of fittings, valves, and other impediments. Moreover, in industry, the letter ‘K’ represents this coefficient and is also commonly … 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.
