МАТЕМАТИЧНА МОДЕЛЬ НЕСТАЦІОНАРНИХ РЕЖИМІВ ТЕЧІЇ ГАЗУ ПО ДІЛЯНЦІ ТРУБОПРОВОДУ З ВИТОКОМ

This work is devoted to the construction of a mathematical model of un-steady nonisothermal modes of gas flow with consideration of kinetic energy in a linear section of a pipeline with a leak. The obtained results can be used at the stage of design, construction and reconstruction of main pipeline networks in order to develop scientifically sound recommendations for improving the safety and efficiency of the pipeline system.
