Efficiency coefficient of water supply and removal as an assessment factor of further operation

Abstract

During operation, pipeline hydraulic characteristics change due to the presence of sedimentary layers in pipes. The efficiency coefficient in an important parameter for the evaluation of the pipeline operation.Purpose: The aim of this work is to prove the necessity of using the efficiency coefficient in the hydraulic analysis of water supply and removal with internal sedimentary layers in pipes in order to predict their hydraulic characteristics with any (measured) thickness of the sedimentary layer.Methodology: Dependences used herein are repeatedly published by the authors.Research findings: Calculation tables are developed to design the reference manual "Calculation tables for hydraulic analysis of water removal in pipes with sedimentary layers".Practical implication: The proposed values of the efficiency coefficient of water supply and removal can be used in hydraulic calculations to predict the hydraulic potential of pipes with sedimentary layers.
