A model piping system with two branch pipes was constructed, and four valves were operated simultaneously. The dynamic flow characteristics inside pipe were theoretically obtained by calculation of the kinetic equation and continuous equation in using the characteristic curve. The dynamic demand load in this model was evaluated by information entropy. The authors analysed the influence of the piping condition and the different in time of each fixture usage. The following results were obtained. 1) Two parametric maximum entropy distribution was useful method to analyse the current flow in water supply pipe system. 2) The value of maximal entropy was large in small radius pipe, and under high pressure, but the length of pipe was not affected.
