DIAGNOSIS OF HYDRAULIC CONDITION OF GAS TRANSPORT SYSTEMS IN THE CONDITIONS OF THEIR INCOMPLETE LOADING

For conditions of non-stationary mode of operation of the gas transmission system, the methods of calculating the actual value of the coefficient of hydraulic resistance are usually based on stationary mathematical models. The analysis shows that the errors in the calculations are up to 30%. In order to reduce the error, it is proposed to use for diagnostic purposes methods based on the model of non-stationary gas movement in the pipes, in particular, a method for determining the value of the coefficient of hydraulic resistance.
