It is important to design pump systems to prevent water hammer in order to avoid potentially devastating conse-quences, such as damage to components and equipment and risks to how to prevent water hammer re-quires a fundamental understanding of fluid prop-erties, governing equations and the design and op-eration of pipe systems, valves, pumps and pump stations. We will present the basic principles of water hammer, application equations, risk poten-tial as well as methods of evaluating water hammer and mitigating and/or eliminating the consequenc-es of these type of Transient events.
