The safe water supply of a population has been one of the most important tasks of mankind for thousands of years and is still a major challenge. In addition to the simple necessity for survival, water is now used in a variety of ways. The most important topics are, in addition to drinking water supply, irrigation, sanitation or electricity generationFor the efficient use of water, pipeline systems are used, which differ in form, material and complexity depending on the application. In order to regulate the flow behavior in pipelines, pipeline systems are almost always used in conjunction with valves. Whenever the flow rate changes in a pipe, whether by a valve position or for other reasons, a change in the speed always involves a change in the pressure. If the speed changes are particularly high, a so-called pressure surge occurs. This passes through the pipeline as a pressure wave with velocities in the region of the body beam until it comes to a standstill due to damping.Based on important physical principles, which are partially treated in this paper, this thesis describes the pressure surge phenomena in more detail, starting with a historical background on pressure impulse calculations up to measures for pressure surge protection. The last section deals with the teaching of physics in the Austrian education system as well as with possible concepts to entice students to study hydromechanics. Two illustrative experiments were developed.
