Absolute Pipe Roughness - EnggCyclopedia

When you have rough pipe, or high absolute roughness value, you would expect to have a high frictional pressure drop in the pipe. Absolute roughness does contribute to the frictional head loss. But it is not the only factor. Rather the ratio of absolute roughness.
