The friction factor is a dimensionless number that represents the resistance to flow within a pipe caused by the pipe's internal surface and the characteristics of the fluid. The factor is influenced primarily by the pipe's diameter, the flow rate, and the roughness of the pipe's internal surface. For galvanized iron pipes, which have a certain degree of surface roughness due to the galvanization process, this factor can significantly affect fluid dynamics.
