Solve liquid-hammer problems

Here are several options

Salehi, F., Dalan Farayand Engineering Co.

Liquid hammer is the destructive force, pounding noises and vibration in a piping system when liquid flowing through a pipeline is stopped abruptly. When sudden changes in flow occur, the energy associated with the flowing liquid is suddenly transformed into pressure at that location. This excess pressure is known as surge pressure and is greater with large changes in velocity. Pipe characteristics such as the materials used in construction, wall thickness and the pipe temperature all affect the elastic properties of the pipe and how it will respond to surge pressures. The thicker the pipe wall and the stronger the pipes and fittings the faster the shock wave. Thin-walled plastic pipe will
