LOL guess I’m not quite as quick as Kevin just yet.

Steve,
It should be:
[cid:image001.png@01DA13DF.08481F30]
Where:
Px= The residual pressure at a particular flow (Qx)
Ps= The static pressure during the flow test
Pr= The residual pressure during the flow test correlating with Qr
Qx= The flow amount correlating with residual pressure being solved
Thanks Jamie.
I just got it from Kevin Hall – I should have called tech support in the first
place…

If
If I remember correctly, you can convert your outlet (Flow and pressure) to
a K factor K=Q/√P then just solve for P with your flow number (Q/K)₂.

Happy Friday everyone:
Once I’ve taken a flow test, I know the formula for adjusting the flow at a
particular residual pressure; it’s published in NFPA 291. But I’ve lost my
notes on the corollary formula for calculating the residual pressure at a
particular flow – does anyone have that hand
