  A water tower ( Water tower / Wasserturm ) also associated as a water tower is a building structure. It is designed to independently regulate the pressure and control the flow of water in a hydraulic system covering a small area where it is erected. A water tower is an object that bases its operation on the simple laws of physics. It has many of the functional features on which the foundations of the water infrastructure module planned for the industrial, urban and railroad sectors are based. Principle of water tower operation How water towers work and for what purpose they are built ? / photo by HarshLight from San Jose, CA, USA A priority feature in the design of a water tower is the search for a suitable site for the future foundations of the structure. The structure, in order to be fully functional, must be built on the highest local elevation. Because the accumulating water in the water tower's tank must be located higher than the water systems located at the customers. The

  Das Prinzip der Sonnenuhr Eine Sonnenuhr nutzt die Position der Sonne am Himmel (misst die Zeit von der Morgendämmerung bis zur Abenddämmerung). Der Schatten der Sonnenuhr nimmt die Form eines sich bewegenden Zeigers an und formt sich während des Tages zu einer geraden Linie. Der Schatten dreht sich tagsüber um den Befestigungspunkt des Stabes auf dem Zifferblatt der Stundenskala. Die Richtung des Schattens, die auf der Stundenskala abgelesen werden kann, entspricht der Sonnenzeit. Die Vielfalt der vorhandenen Sonnenuhren ist vor allem auf die unterschiedliche Form und Ausrichtung des Zifferblatts zurückzuführen. Die häufigste Variante ist die vertikale Sonnenuhr mit einem flachen Zifferblatt an einer vertikalen Gebäudewand.

Es ist eine Tatsache, dass Sonnenuhren den Menschen seit Anbeginn der Zeit nicht
