WebOmission of frequency-dependent hydraulic resistance (skin friction) during modelling of the water hammer phenomenon is unacceptable. This resistance plays a major role when the transient liquid flow occurs in rigid-walled pipes (steel, copper, etc.). In the literature, there are at least two different modelling approaches to skin friction. The first group consists … WebDec 5, 2011 · One of many great attributes of HDPE pipe is its low friction factor. HDPE pipe is less impaired by flow reduction or pressure loss from the fusion beads than the turbulence in a comparable system made of PVC push joints. Using a material that has less flow reduction and pressure loss doesn't mean that there isn't impairment.
