Pressure drop in pipe fittings and valves | equivalent …

The minor loss in a system component can be converted to the "equivalent length" of a pipe or tube that would give the same major head loss. Equivalent lengths of fittings like elbows - regular 90 o, long radius 90 o, regular 45 o tees - line flow and branch flow return

Tech Tip #2: Equivalent Lengths - Southwark Metal Mfg. …

This value is the comparison “length” of this fitting to an equivalent length of straight pipe or duct. For example, each elbow used is equivalent to 30 feet of straight pipe or duct. Southwark Metal Mfg’s sheet metal pipe, ductwork, and fittings conform to this system of equivalent lengths as well as conforming to industry national standards for describing residential fittings.

Pipe Fitting Losses - CheCalc

Pipe Fitting Losses Pressure loss in a pipe due to fittings such as elbows, tees, valves, expanders and reducers based on 3K and 2K method.

Duct Design 3 — Total Effective Length | Energy Vanguard

Each fitting has an effective length that equates its pressure drop to an equivalent amount of straight duct. When you add up the effective lengths of all the fittings and then add that nuer to the length of the straight sections in the most restrictive runs in the
