Water hammer and surge chamber

In structures such as hydroelectric power plants, or in systems for supplying water, changes in flow rate result in pressure fluctuations. For example during startup and shutdown of hydraulic machines or by opening and closing shut-off elements. There is a distinction to be made between rapid pressure changes that propagate with high velocity (water hammer) and slow pressure changes caused by mass oscillations.
