Abstract:

In the first pressure section of the Ecker long-distance water pipeline, considerable decreases in the rate of flow occur in years of low operation which can be traced back to a special corrugation of the film of grease deposited in the system. The small depth of the deposit in relation to the pipe diameter and its technical flow behavior, different in nature from that of hitherto investigated roughnesses, make it probable that it is a matter of a new specific type of roughness. This discussion is preceded by a review of the general theory of flow in pipe lines.
