| Abstract: | In this paper the vibration problem is analysed for the fluid flow in a hydraulic pipe with a beginning or a shutting at the downstream under the upstream sinusoidal pressure pulse. It results in the initial-boundary value problem for a first order quasilinear hyperbolic system- of partial differential equations with two variables. The hydraulic, pressure formula for nonviscous fluid and viscous fluid is given. |
