Program for hydraulic net calculations

[samuelo]

Hi all,

I have to study a complex net of piping, with many centrifugal pumps connected in parallel that don't work simultaneously all the time. Do you know any program (free if possible) that can help me?

I need to have the possibility to insert the pump carachteristic curve, not only the working point.

Thanks in advance

EPAnet, available at

http://www.epa.gov

for free, it is used to model networks of piping systems for water distribution, the pump section include the ability to enter a multipoint pump curves, the controls section will enable which pumps operate under which conditions, I assume you are working with water because the equations are based upon Hazen Williams.

I see I can model also hydrants or sprinklers with this program.

Thank you, hydrae.
