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. What should happen is that the modeler should show the work that was done to calibrate the model to the decision maker and ask, “Do you think the model will meet your needs?”
SewerGEMS é capaz de dimensionar automaticamente tubos, bueiros e estruturas hidráulicas além de determinar cotas de fundo. Além de ser capaz de dimensionsionar atendendo diversas restrições definidas pelos usuários durante o dimensionamento automatizado, como faixas permitidas de inclinação, velocidade recobrimento e tensão trativa.

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 are making them. Most researchers are graduate students and their advisors, who have never worked on real-world problems. As a starting point for their work, they rely on prior research papers that contain assumptions that the prior authors did not mention. As a result, real-world complications are often lost in legacy papers.
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 forces dominate. A large Froude number indicates rapid flow, while a small number points to tranquil flow.
There are several reasons. First, the pressure is so high and constant in water systems in most developed countries that the effects of pressure on flow is negligible.
The most common question in pump selection these days is whether to use variable or constant-speed pumps.
