Compared to steel pipe, CPVC has what level of hydraulic friction?

Explanation:
The main idea is that the roughness of the pipe’s inner surface affects hydraulic friction. Fluids lose energy as they slide along pipe walls, and rougher interiors create more turbulence and resistance. CPVC typically has a smoother interior bore than steel, especially compared to steel that can be roughened by rust or scale. That smoother surface reduces the friction factor and, for the same diameter and flow rate, lowers the head loss per unit length. So, CPVC produces less hydraulic friction than steel.
