Abstract
The load in the water supply system of buildings occurs in using fixtures and the variation of flow quantities is remarkable, and the characteristics of load are different according to a kind of fixture. It is necessary for designing a plumbing system to get hold of dynamic characteristics of load and to analyze the behavior of the current in this system. In this paper, the authors constructed a model piping-system with two branch pipes, and investigated and analyzed the relations between the characteristics of flush valves for experiments and that of numerical simulations. Then, the dynamic characteristics of the simultaneous load in water supply was evaluated by information entropy.
