Thank you all for your feedback.
We sometimes have to work with a range of dia from 800 to 2000mm, and I have seen the telescoping you are describing in some studies, but not in real life.
Besides, the pressure rating in water works is rarely above 25 or 40 bars, so the rule of t > D / 120 often...
Good afternoon all,
I'd like your help to understand some hydraulics.
Let's consider a centrifugal pump for clear water, installed at z=0m, with a 10 km discharge pipeline, pumping into a tank at z=100m, along a linear profile.
Let say that the losses are roughly 50m, hence a TDH of 150m under...
