The fixture unit method (in some places called fixture value method) was developed by Roy B. Hunter from the US Bureau of Standards, based on research conducted by Hunter in the 1920s and 30s (Hunter, 1940). Every fixture in a...
They are nonlinear, partial differential equations which are about the worst kinds of equations to solve. About the only things that can make them worse are changes in state (e.g. steam condensing) or non-Newtonian fluids (e.g. mudflows). Numerous researchers have...
One of the most important inputs to transient analysis is the speed of the pressure wave (called celerity) moving through the pipes. The speed depends on the fluid properties and pipe properties and has a significant impact on the magnitude...
Flushing water mains is one of the accepted methods for cleaning a water main and reduce water quality complaints due to color and turbidity, or to bring fresh water with a high disinfectant residual into an area with low disinfectant...
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...
