Abstract
One of the main tasks of technical diagnostics of pipeline systems is to ensure their reliable and at the same time energy-efficient operation. In this work, we have searched for and developed the basis for constructing mathematical models of new informative parameters for diagnosing the technical condition and efficiency of pipeline systems. It is shown that the capacity of a pipeline decreases when it acquires an elliptical cross-sectional configuration. It is substantiated that the presence of small leaks in pipeline systems causes a loss of flow stability in the pipeline, the emergence of turbulent flow zones, which reduces the efficiency of the pipeline.
