ESTABLISHING THE PIPELINE EFFICIENCY COEFFICIENT FOR GAS TRANSPORTATION IN GAS PIPELINES UDC 622.691.4

Abstract

Under conditions of steady motion, the resulting pressure losses due to friction along the length cause a number of characteristic features of the movement of a real gas compared to the movement of incompressible liquids through pipes. At the same time, the physical properties of the gas, the mode of movement, temperature and viscosity, which have a direct impact on the value of the gas pipeline efficiency coefficient, were taken into account.
The article provides an analysis of methods for calculating the efficiency coefficient depending on changes in hydraulic resistance, which characterizes the throughput capacity of the pipeline. A calculation of its value is presented based on production data for steel pipes. The dependence of the required power for gas transportation on the efficiency coefficient of gas pipelines is given.
Based on the research results, equations were derived to determine the coefficient of hydraulic resistance of a pipeline when a gas-liquid mixture moves through it and a formula was established that characterizes the efficiency of the system under appropriate conditions.
The developed dependencies help to establish the maximum throughput of gas pipelines both along main and field pipelines.
