The friction factor is a measure of the resistance that a fluid experiences when flowing through a pipe. This resistance can vary greatly depending on the pipe's material, surface roughness, diameter, and flow rate. For galvanized iron pipes, the friction factor is crucially important because it directly affects the flow efficiency, energy consumption, and overall performance of the piping system. Higher friction factors lead to increased energy costs and reduced flow rates, making it essential for suppliers to understand how these factors interact.
