摘要：
The distribution of water losses due to leakage from the water network is studied as the first step of the mathematical model calibration procedure. In order to calculate the leakage from pipe an empirical formula which takes into account the length of pipe and mean pressure, and also contains certain coefficients, is used. This leakage is carried to the terminal nodes and distributed between the nodes proportionally to the pressure in the nodes. For determination of leakage the measured pressure in control nodes is used. For evaluation of pressure in other nodes an iteration process is applied which determines the leakage and pressures intermittently. Computational results for water distribution network of the city centre of Tallinn are presented, demonstrating the applicability of the method.
