WebEQUIVALENT LENGTHS OF PIPE FITTINGS AND VALVES For SI: 1 foot = 305 mm, 1 degree = 0.01745 rad. Note: Values for welded fittings are for conditions where bore is not obstructed by weld spatter or backing rings. If appreciably obstructed, use values for “Screwed Fittings.” 1.

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.
