Water & wastewater: A note on the topic of water hammer

摘要

Water hammer is the study of how a fluid system transitions from one steady state condition to another steady state condition, generally in terms of pressure and velocity changes that occur during the transition phase. It manifests itself as pressure waves travelling at the speed of sound through the pipe network. It is a common event in pipe distribution systems. It can cause significant impacts to pipe networks and be dangerous to plant and personnel. Compu puter modelling software available to model water hammer events.
