In case he just reads the thread titles. Will Kiril and Wet Boots please pose the question the way you want Dr.Pressure to consider it.

Once more, then. In a home with a basement water meter, I do a flow-and-pressure test, and come away with a dynamic pressure reading, call it DP, and the flow at which it was measured, call it F. I also measured the static pressure, call it SP ~ Now I want to calculate what my flow will be at a dynamic pressure different than the one that I measured.
For the sake of simplicity, it will be assumed that the measurements all apply to a point just downstream of the water meter, where my takeoff will be. In real life, the plumbing in some houses would introduce some difficulties into getting measurements this 'pure' - but it can be done. There are no PRVs anywhere upstream of the measurements.

i sense he is calculating the equations right now.

In real life.
Always worked for me.
