Résumé

Inevitably leakage is the main cause of water loses in pipeline network. Total water loses in network depends from many parameters and working parameters in heating plant: working pressure, temperature, largeness of the system and content of water in the network. In this paper dimensional analysis was used for performed specific leakage coefficient which depends from working pressure, content of water in the network and cinematic viscosity. Temperature operation mode has indirectly influence: cinematic viscosity depends from temperature. Here in Serbia we often make comparison of water loses with networks in Denmark, where is district heating more developed. But, due to ground configuration, in Serbian heating plants working pressure are bigger and that’s why water loses are bigger. If we operate with this leakage coefficient we will have more reality comparison. Parameters for estimate water leakage without working parameters (for example yearly changes of water content) have not given a real picture of water leakage.
