Hello
There is a Pump which has to deliver water from a Reservoir to several Junctions. The Junctions have dissimilar Elevations and Demands. There is no any Tank or Reservoir at the end point of network. How can define a sufficient Pump? How can calculate ONE Elevation and ONE Demand to select sufficient Pump from manufacturer product catalogs?

Please have a look at example 3 in the sample models.

If I'm understand your question correctly, you may want to look at this Support Solution on system head curves for systems with no downstream storage (you can find a lot of previous forum discussions on this subject, too.)

You may also want to take a look at our Advanced Water Distribution Modeling and Management book for general modeling advice.

I studied Example no.3 in the models. It is a closed system with one pump. Network contains several Junctions with dissimilar Elevations and Demands. The default Pump is Pump-Definition -2. Now this is the question exactly:
How did Designer design a sufficient Pump (for example Pump Definition -2) for this network?
My question is about how of pump definition when you do not have ONE specified Demand with with ONE specified Elevation for it. Here we have a network which has many Demands with many Elevations.

Thank you very much. I will focus on this Wiki page.
Would you tell me which page or section of the book you referred to it?
Simbaa,
You may also want to have a look at this wiki entry which explains how you can estimate the desired head for your pump given you know the flow rate you want.
