Relative Roughness The quantity used to measure the roughness of the pipe's inner surface is called the relative roughness, and it is equal to the average height of surface irregularities () divided by the pipe diameter (D). Surface finish, cleanliness and lubrication of the mating surfacelargely determine the actual frictional resistance between mating surfaces. 1 inch stainless steel pipe. An exception is cylinder bores where oil is retained in the surface profile and a minimum roughness is required. The valves I am considering are reduced bore valves and did think that the friction factor would be very small -So thank you for clearing that up. When you have rough pipe, or high absolute roughness value, you would expect to have a high frictional pressure drop in the pipe. unless alternative specifications are specified.
