Abstract

Fresh water on the ship must flow from the lowest compartment in the engine room to the top of the platform. The pressure tank, or hydrophore, is a freshwater distribution system widely used in multi-storey buildings, including ships. Hydrophores are used in multi-storey building construction, including on ships, only as temporary holding tanks. The system acts to raise water from storage tanks or wells that are located lower. These systems need to be operated and maintained by competent people. The competence of competent crew members will be able to overcome the problems that occur. Issues that arise in the hydrophore system are very diverse. However, one thing that impacts a hydrophore system disruption is that the supply of fresh water to the entire ship is disrupted or does not flow. The purpose of this study is to design a hydrophore system so that it becomes a prototype that can be used for learning. When the hydrophore prototype has become a practical medium, it can be used as an engineering tool to study many phenomena. The results of the study can be concluded that when water flows through 1 pipe alternately, the pressure difference with the tank is about 0.1 - 0.2 bar. When water is flowed through 2 pipes, the pressure difference with the tank is about 0.2 - 0.4 bar. There is a pressure differential of roughly 0.2 to 0.5 bar when three flow pipes are opened at the same time.
