Abstract: The large complex piping systems under unsteady operating mode are considered. Such systems can exemplify the typical systems with distributed parameters. General mathematical model of transients in piping systems is demonstrated. This transient is described by the solution of the graph-defined mixed problem. The dimensionless analysis is given for principal physics of the water hammer equations' simplification. System with lumped parameters consisting from inertial and elastic “blocks” is used for substitution the assumed piping system with distributed parameters. The convergence of such a kind of approximation is considered. The water hammer problem for single pipeline is used for testing the obtained model. The comparison "thorough" system with simplified one was realized for some models.
