Water hammer in water distribution system
Keywords:Water hammer, water distribution systems, valve, pump rising pipeline system
The hypothesis of Allievi about the uniform valve closure in the first part of an urban water distribution network in order to minimize water hammer, has proved to be unacceptable in view of the theoretical and experimental results that are shown in this paper. Further considerations are made about the unsteady flow in pump rising pipeline systems according to the most recent developments, to mitigate water hammer damages. Furthermore, it is noted that water hammer studies mainly concerned pipeline systems in hydroelectric power plants while less attention was paid to water supply pipeline systems considered in this work.
