4. The straightening vane is installed in the pipeline at a distance of 1
2
pipeline’s DN from the last source of hydraulic resistance with respect
to the flow direction. When installing the straightening vane, the length
of a straight run before PEA is determined as the distance from the
source of hydraulic resistance to PEA.
