FHyd Flow data for Pump Curve

I'm modeling a new network between 2 separate existing waterlines that will be connected to. On each of those 2 supply lines, we ran flow tests on 2 hydrants. I understand the feedlines into the new network is represented by a resevior+pump, of which the resevior is set to the closest fire hydrant elevation on the particular line and that the pump curve is derived from the flow data of that particular fire hyd. On the one feedline, we have the nearest FHyd data as static 60/piezo 25/el 1301 and the other FHyd on that line as static 80/residual 72/elev 1265, with 1100' of 6" line inbetween them. What data do I use for the "pump" curve at the higher FHyd ?

Re: FHyd Flow data for Pump Curve

Answering myself, from what I figured so far, the piezo reading is converted to head (piezo x 2.31), then added to FHyd nozzel cl elev as the resevior ws elev.... connect resevior to system with a large dia line, so there is no friction introduced... the 1st node should reflect the piezo pressure, at flow zero.
