The situation raised by O.Piller is not a rational proposal from an engineering point of view. Let Qmax be the flow rate transferred between the two tanks when both valves...

It seems that the EPANET 2.2 result also depends also on the pipe properties. I have reconstructed the example in SI units, with diameter 200 mm for all elements and...

Thank you Lew for your quick and effective response. As far as I am concerned, the problem has been solved, so I propose to close this issue. I have many...

Continuing with the same example, I have now checked that the coefficient of minor losses at the open valve is correctly taken into account for all other valves, except for...

I understand that a valve cannot have losses lower than those corresponding to an open valve. This concept is being applied to the remaining valves. If a user wants to...

The possibility of relating the dimensionless loss coefficient k of a valve to its position represents an important advance in relation to the types of components currently offered by the...

Thank you @LRossman for accepting my proposal, in order to bring EPANET little by little closer to the real world of engineering. There was indeed a small error in expressing...

And regarding the calibration of valve behaviour from SCADA data, which @jamesuber is so concerned about, the use of Kv is simpler than using k, and its values are more...
