These days, I get involved in a lot of discussions about “digital twins”. One of the most common questions is, “What is a digital twin?” With so many people talking about this, you would think that by now there would...
Simulating low pressure in your hydraulic model can identify/confirm the cause of the problem and point you to the right solution....
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....
Real-world problems are ugly, and simplifications and assumptions need to be made to make the problem solvable. The researchers tend to gloss over these assumptions—if they mention them at all. I think many researchers may not even realize that they...
Last fall, I did a hydraulics quiz and readers seemed to enjoy it. So, here’s another one. See how you do and feel free to share. Answers are at the end, but don’t peek....
In my work in water and wastewater hydraulics, the two that show up most of the time are the Reynolds number and Froude number. A small Reynolds number indicates that viscous forces dominate, while a large value says that inertial...
