    Maximum Flow Through 3/4" Copper K?

    Thank you fel3 and bimr for your thoughtful input. I'm also glad to see others have had this question to what seems so "simple" a problem to the lay person. fel3 - I very much appreciate your detailed steps. I will "do my homework" and post back in a couple days or so. Hope you get some sleep:)

    Maximum Flow Through 3/4" Copper K?

    Hi there, I'm a new EIT and starting to get more involved with small water systems. One question that keeps on cropping up is "What is the maximum flow possible through [X] diameter pipe?" For a practical example, let's use a 6-inch watermain in the road (say @50-80psi Static) and a connection...

    First Time Creating a System Curve

    Thanks for the reply. That makes much more sense that the system curve should be taken at the pump node. (I had been measuring the head at the end of the piping system, after the HGL had fallen.) I've attached a simple sketch of my system to clarify. You'll see the system of interest in red -...

    First Time Creating a System Curve

    I'm an EIT looking for advice on how to properly create the system curve for a simple water distribution network. I understand conceptually that it is the resistance the pump will "see" due to friction, fittings, etc. I was told there is only one unique (H vs Q) curve for a given system, but...
