Opis

The disturbance which spreads in a form of pressure wave occurs in transient fluid flow conditions. The disturbance speed in the pipes under pressure can reach the value close to the speed of sound in the medium. Course of the disturbance is so complex that it cannot be described in a simple and direct way. Water hammer phenomenon is accompanied by the formation of the oscillatory motion of the pipes in the system. It may even lead to significant displacement of the pipes, which in extreme cases can lead to fire protection system mounting damage. Therefore, correct identification of the dynamic load affecting the system during hydraulic shock wave propagation is essential to increase operational reliability of fire protection systems. In the book the results of the measured forces and the associated displacements are presented.
