bulgariaWhat is Equivalent Pipe Length Method - Definition

The equivalent length method ( The Le/D method) allows the user to describe the pressure loss through an elbow or a fitting as a length of straight pipe. This method is based on the observation that the major losses are also proportional to the velocity head ( v2/2g ). The L e /D method simply increases the multiplying factor in the Darcy-Weisbach equation (i.e. .L/D) by a length of straight pipe (i.e. Le) which would give rise to a pressure loss equivalent to the losses in the fittings pipe fittings equivalent length table in bulgariaAPPENDIX A SIZING AND CAPACITIES OF GAS PIPINGAPPENDIX A 2011 OREGON RESIDENTIAL SPECIALTY CODE A-3 TABLE A.2.2continued EQUIVALENT LENGTHS OF PIPE FITTINGS AND VALVES MITER ELBOWS3 (No. of miters) WELDING TEES VALVES (screwed, flanged, or welded) 1-45° 1-60° 1-90° 2-90°5 3-90°5 Forged Miter3 Gate Globe Angle SwingAPPENDIX F SIZING OF WATER PIPING SYSTEMC Step 7, Column 6 Select from Table F103B or F103C the equivalent lengths for the trial pipe size of fittings and valves on the section.

Equivalent length is exactly what it sounds like. An elbow, a tee, or any other fitting that causes a change in direction will cause pressure loss. The way this pressure loss is accounted for is the equivalent length. The equivalent length is just the equivalent amount of straight pipe it would take to create the same pressure loss.
