Water supply curve

Flow axis scaled to the 1.85 power (NFPA 291 paper), so the supply plots as a straight line
Static 72 psi Test 1,138 gpm at 58 psi Available 2,311 gpm at 20 psi

How the flow was worked out

Each outlet's flow is 29.83 x c x d² x √p (c the outlet coefficient, d the outlet diameter in inches, p the flow pressure in psi). The flow at 20 psi is that flow x ((static - 20) / (static - residual))^0.54, per NFPA 291.
