hydraulic efficiency and its change over time, energy dissipation, internal energy, efficiency factorAbstract
The problem of energy dissipation in the main gas transportation on linear regions of pipelines and its impact on the hydraulic efficiency factor reduction is considered in the paper. The results of analytical studies of the potential and kinetic energy conversion into internal energy are presented. The primary objective of the research is to determine the effect of energy dissipation in the pipeline throughout the entire route on the hydraulic efficiency of the gas transportation system as a whole, and consequently on the hydraulic efficiency factor reduction in particular. In the paper, the above analytical studies are given and compared with experimental data. Positive convergence of predicted and actual results and their impact on the hydraulic efficiency factor was revealed. These findings are important to take into account for the operating gas transportation companies. The results allow to increase the capacity of main gas pipelines and thereby increase the hydraulic efficiency factor. The principle of implementation of the task and use of its results is demonstrated.
