Hi,
We know that in many places a great portion of the "demand" is due to water loss and we also know that water leakage is directly proportional to the system's pressure. I would like to know, if you are doing and how you are doing to model water losses.
Here where I work, we are loading losses using the unity line method and for the real demand we choose a method based in the data we have.Today I saw that there is a way we regulate demand depending on pressure, but it doesn't seem to be possible to choose which demand of the collection of a junction the pressure dependent will be applied. It would be nice to say that the demand by loss is pressure dependent and the costumer demand isn't.Thanks,
