WebbThe friction head loss values in the fluid flow tables below are based on this formula, and Corzan CPVC piping’s surface roughness had a constant of C = 150. The lower the C Factor, the higher the friction. For reference, consider the surface roughness constants for both new and old piping materials: WebbMost of today’s water supply systems are based on plastic pipes. They are characterized by the retarded strain (RS) that takes place in the walls of these pipes. The occurrence of RS increases energy losses and leads to a different form of the basic equations describing the transient pipe flow. In this paper, the RS is calculated with the use of convolution …
