Pipe Friction Factor Calculation

12/12/2013· K factor can vary greatly with plastics, as there are alot of factors that can come into play. The type of benders that are used. i.e is the material being heated on both sides or just one. is the heat hotter on top or bottom. are you bending towards the heated side or away from the heated side. how big is the area being heated, and how does this relate to the radius being bent.

Estimating Hazen-Williams Coefficient for Polyethylene …

Results of this investigation indie that the average Hazen-Williams coefficients are 129, 136, 144, and 148 for pipe diameters of 13, 16, 19, and 22 mm, respectively. The differences between the measured friction losses and those calculated based on the average Hazen-Williams coefficients are small and vary from 8 to 14% at pipe diameters of 13 and 22 mm, respectively.
