Because of the importance of water hummer and it’s big impact in
pumping pipes, an analytical study of water hummer resulting from
the pumping station abruptly stopped working (due to a power
outage on water pipe line that conveys water from groun
d open tank
to three overhead open tanks was conducted, and without means of
protection from water hummer .
maximum and minimum pressure values and the location of each of
them in the network have been identified.
It was found that the pump trip caused a transient state with
negative pressure along the pipe system. The values of maximum
pressure were less than the pressure tube run.
An analytical study was done to explain the
relationship between the performance of gas accumulator, surge
tank and vacuum breaker valve and the profile of the pipe.
The study proved that effectiveness of protection means vary
according to the longitudinal path of pipe.
