The major losses of fluid flow in plastic pipes due to friction are usually few or negligible in some cases, and this is due to the assumption that the value of the friction factor is small (small roughness). This work aimed to estimate the friction factor vs Reynolds number and to compare against previous data. The friction factor was estimated using an experimental model consisting of a polypropylene pipe with a nominal outside diameter of 16mm and length of 8.5 meters, connected by eighteen elbows. The results showed that the practical coefficient of friction factor is less than the value using the Basilus equation for smooth pipes, indicating that polypropylene pipes are smoother. Additionally, the numerical formula similar to the Basilus equation was found to be 1.92312e-509. Finally, the amount of energy lost due to the friction factor in PPR pipes is small compared to other types of pipes, attributed to the extrusion process that makes the inner walls smooth, though it cannot be neglected in fluid flow.
