In calculating steady-state flows of water distribution networks, one of the conventional assumptions is that the consumption outflows are constant. In actual networks, however, outflows depend on the pressures. In order to achieve more precise analysis of actual networks, we present in this paper a new method of steady-state flow calculation under the condition that outflows are given as functions of pressures. The newly proposed method for dealing with pressure-dependency of outflows is based on the mesh-flow analysis and is much more efficient compared with the previous method proposed by the authors based on the traditional node-head analysis. It is especially effective for the analysis of fire prevention water networks installed in temples, shrines and villages with many cultural buildings.
