In this paper, a theoretical comparison was made of the state of the current flow in the pumping networks between the two methods, the first hydraulic analysis, the most common or so-called method of properties and is used in the analysis on the time range and the second method is called the method of frequency range. For the purpose of comparison, two types of networks that suffer from the phenomenon of transitional flow or so-called water hammer were studied. The first is a simple network without extensions or fittings. This kind of network is far from reality, because real networks are usually many extensions and branches. The second network is more complex and closer to reality. The results of the analysis showed that the two methods gave identical results to the first network. However, the results were not identical in the second most complex network, where it was clearly observed that the first method felt that the water hammer phenomenon was more than the second method from reality.
