AWWA DSS71289 Field Testing and Hydraulic Modeling Locate Closed Valves in Distribution Systems
Conference Proceeding by American Water Works Association, 11/01/2009
Roberts, Meg; Widderich, Kevin
Full Description
This powerpoint presentation begins by providing a brief overview of hydraulic models, defined as computerized pipe network analysis thatuse energy loss equations. Hydraulic models are used to determine the flow rates,pressures, and water quality in theindividual sections of a pipingnetwork. Field testing is presented, and includes themeasurement of flow, pressure, or waterquality indicators under certain conditions. Topics presented include: hydraulic grade line (HGL) tests; hydrant (fire) flow tests; closed valves; and, examples from North Carolina municipalities. Includes figures.Cart
