Fluids are often transported under pressure. Think of drinking water networks, certain industrial process pipes and sewage pumping stations. If these systems are not well designed this may lead to adverse consequences for the infrastructure. One of the possible consequences is water hammer, which occurs when a sudden pressure change caused by the activation or deactivation of pumps creates a pressure wave through the pressure pipeline, which may lead to high overpressure or underpressure in the pipeline network. Such pressure may be so strong that the infrastructure explodes or gets damaged severely due to cavitation.
