I am looking for roughness values for an old bitumen lined pipe (approx 50 years old). The pipe's internal bitumen coating is still intact with blisters and cracks that formed over the years. The blisters however have'nt started to come off yet. I need to model the flow through the pipeline and I would like to use the correct order of roughness.
