when you talk like that.

John Siegenthaler has written software called Hydronic Design Toolkit that should provide you with what you need. It's available through the RPA website:

You can also email John to make sure it's included in the software:

JohnSiegen@aol.com

Best wishes,

    Reverse return hot water pipe design

    The calculation of flows in a reverse return seems to require a simultaneous solution of non-linear equations.
    ( head = constant * flow to the 1.75 power ).
    Is there software that will calculate the flow in each segment of the system, given the pump head and the geometry of the network?
