dc.description.abstractLiterature on the methods for defining the equivalent roughness of the internal surface of a measuring pipeline was analyzed. The equation for calculating the hydraulic resistance coefficient of friction of natural gas on the internal surface of the measuring pipeline was developed. The equation for calculating the equivalent roughness of the internal surface of the measuring pipeline was obtained. This equation provides improvement of accuracy of natural gas flow rate and volume measurement by means of the differential pressure method.uk_UA
