Abstract: In a pilot study for the diagnosis through transient tests of the water distribution systems of Milan, Italy, hydrants were used for both pressure measurement and pressure wave generation. In the field tests, the maneuver ...

Abstract: Torricelli’s formula is often used to define the dependence of the leak outflow on the flow conditions inside the pipe and on the leak characteristics. Some tests carried out at the Water Engineering Laboratory of the ...

Abstract: Transient tests can be reliably used for the diagnosis of pressurized pipe systems. As a matter of fact, the pressure signals acquired during these tests can reveal the presence of anomalies, e.g., leaks, since any ...

Abstract: In this paper, the results of laboratory transient tests concerning the interaction between a pressure wave and an in-line device are discussed. Transients are generated by means of a fast and complete closing of an end ...

Abstract: The relationship between leak outflow from a damaged pipe and flow condition inside the pipe plays a crucial role in pressurized pipe systems management. As an example, this relationship is used in leakage reduction ...

Abstract: In this paper, the reliability of a transient test-based technique as a powerful tool in the management of real supply pipe systems is shown. The pressure signal acquired during the first phase of the single completed test ...
