Equivalent length refers to the elbow and other parts of the tube with consideration to the pressure lost after
the conversion length.
The formula is as follows:
Equivalent length = actual length of pipe + number of elbows x Equivalent length of various elbows
The length of each branch is 0.5m, with the equivalent length of the elbow as follows:
Diameter
Equivalent length
Diameter
Equivalent length
Elbow(m) Elbow(m)
φ9.52 0.18 φ28.6 0.50
φ12.7 0.20 φ31.8 0.55
φ15.88 0.25 φ34.9 0.60
φ19.05 0.35 φ38.1 0.65
φ22.23 0.40
φ41.3 0.70
φ25.4 0.45
Note:
The equivalent length of elbow in the table above aims to fulfill installation standards: the pipe bending radius of curvature is R ≥ 3.5D (D for the pipe diameter),
about ≥ 3/4 of the original diameter before the pipe bending deformation. If the elbow bending radius does not meet the above installation standards, the
equivalent length is to be calculated separately (the smaller the bending radius, the longer the equivalent length).
