gas balance

On an invariant of a non-stationary model of pipelines gas flow

A problem of gas balance analysis in the gas transportation system objects and the factors of influence on the accuracy of its installation are considered.  It is shown that the problem of accuracy of calculation of the individual balance indicators can be effectively solved.  For this purpose, the invariants of the mathematical model of gas flow are used.  The carried out computational experiments have confirmed the sufficient accuracy of the suggested approach.
