Permissible Pipeline Roughness as the Most Important Factor in Ensuring the Quality of Liquid and Gas Transportation

Some works are analyzed; the analysis results are used to propose to apply the Reynolds number as an indicator of the quality of a liquid (gas) flow; and the parameters of permissible roughness should be considered among the main quality indicators in a pipeline design. The necessity of updating and refining the existing standards by standardizing of the permissible roughness is substantiated.
