Those of you who work with water distribution systems generally need to determine the flow that can be delivered to a fire at some minimum residual pressure, which in the US is 20 psi in most jurisdictions. In most cases,...
In order to do any kind of hydraulic modeling, whether it is for water distribution, sewage or stormwater, it is necessary to determine the head loss over a range of flow rates. Much of the early days of hydraulic engineering...
Modeling pump status or speed or valve position is generally pretty straightforward in most automatically controlled systems....
Pressure and water quality could deteriorate in the customer’s plumbing system. The problem has become more acute with regard to the COVID-19 crisis in that many buildings such as schools, hotels and offices have been shut down for extended periods...
Water utilities everywhere struggle to reduce real water loss using a variety of tools from acoustic leak detection, to water audits, to pressure anomaly detection, to ground penetrating radar, to pressure management. Each of these addresses a portion of the...
Another issue lies in the personas who are asking and answering the question. Usually the decision maker (i.e. design engineer or system operator) will ask the modeler, “Is this model calibrated?,” and expect the modeler to answer yes or no....
