Water hammer is still a "bugbear" to water works men. It seems to be forever with us in causing breakage and leaks in the distribution system. It is of concern to the superintendent because his service of supply is closely allied with the work of architects, engineers, and plumbers in making satisfactory distribution systems in buildings.

Water hammer could be damped in pipe networks using a short piece of plastic pipe of a diameter much larger than the diameter of the pipe in which water hammer is to be controlled. Experiments using four different polyvinyl chloride (PVC) pipe sizes, and different damper parameters and materials show that the device can effectively reduce pressure ...

The invention provides apparatus for shaking structures such as fins in a fluid agitator, shaking tables, shaking screens, conveyors, or the walls of bins or hoppers. The apparatus is driven by a hydraulic driving system in which high pressure pulses are generated by repeatedly creating water hammer within a conduit.

Viscous Dispersion in Water Hammer
Journal of Basic Engineering, 1960When a column of fluid moving with uniform velocity is instantaneously stopped at the downstream end a pressure wave is propagated upstream. In an inviscid fluid the wave is a step discontinuity, and the pressure so calculated serves as an easily obtained upper bound for all practical “water-hammer” problems, the exact solution of which may be either ...

Water Hammer Causes Water Main Breaks
Journal of Pressure Vessel Technology, 2019Abstract Most underground water main breaks can be stopped, since the technology is now available to evaluate water system piping failures and determine corrective actions. The problem is defined in terms of several variables: (1) Water hammer is the initiator of nearly all underground water main breaks.

Practical Aspects of Water Hammer
Journal AWWA, 1948values range from 35 per cent below to 500 per cent above. The graphic method for solving water-hammer problems effects material simplifications, and for some complex cases it offers the only practical means for calculating surge pressures. Much time and effort has been saved by the use of this method, but specialized knowledge is still required to ...
