Here, with the valve in the pipe closed, the pipeline will have a static water flow condition. Hence, kinetic energy = 0

A pressure reducing valve is exactly what it sounds like, a valve that reduces the water pressure in your home.

Here, the rise in pressure inside the pipeline could be measured using Joukowsky’s Formula. Pressure rise, pr=w*a*v/144g ; where w is specific gravity of liquid, a is velocity of pressure wave in m/s, v is change in flow velocity in m/s, g is gravitational constant.

609.10 Water Hammer: Building water supply systems where quick-acting valves are installed shall be provided with water hammer arrester(s) to absorb high pressures resulting from the quick closing of these valves. Water hammer arresters shall be approved mechanical devices that comply with ASSE 1010 or PDI-WH 201 and shall be installed as close as possible to quick-closing valves.

The pressure shock wave, with its energy hits and pushes the piston inside the WHA upwards, compressing the pre-charged air and loses its energy. Once the effect of the peak pressure shock wave is absorbed, the piston gradually returns back to its original rest position. This tendency of the piston inside the water hammer arrestor to revert to its original position is the reason behind the working of a water hammer arrestor.

As the valve is suddenly closed, the flowing water with its energy (as explained with the above formula) hits the valve, bounces back and collides with the approaching stream of water. The collision that happens in the pipeline triggers an enormous pressure spike in the pipeline to create this undesirable noise and shaking, called water hammering. (Think of a train engine applying a sudden brake causing the compartments to collide with each other).

The picture shown here illustrates how a Water Hammer Arrestor functions. This simple device can effectively control the undesirable effects of water hammering and is widely being used in the industry. The operations of the WHA can be compared to the working of a shock absorber used in a motorbike.

As per the example used here, a standard 1/2″ supply line with water flowing at 1.8 m/s can generate a pressure rise of 29 kg/cm2 above the flow pressure itself. The resultant shock wave bounces back and forth within the supply line until it reaches a point of relief in a larger main where the velocity is much slower.
