Journal Title: Energy Engineering and Control Systems - Year 2015, Vol 1, Issue 2
Abstract
Methods for measuring the roughness of the internal surface of a measuring pipeline for projected rectilinear sections of a measuring pipeline and for rectilinear sections that are in operation have been determined. The new equations for calculating the hydraulic resistance coefficient of friction of natural gas on the internal surface of the measuring pipeline, the average value of natural gas pressure along the section of a measuring pipeline and the equivalent roughness were obtained. These equations provide improvement of accuracy of natural gas flow rate and volume measurement by means of the differential pressure method. The equation for calculating the Reynolds number from the conditions of the roughness measurement in real time was obtained. The technique of selection of methods of the roughness measuring was presented. Functional scheme of process automation of measurement the equivalent roughness of the internal surface of the measuring pipeline was developed.
