Pump Chart Generator

Build a print-ready pump chart table by flow (GPM). Training estimate. Formula: PDP = NP + FL(supply) + FL(attack) + Appliance + Elevation.

Inputs

Flow min (GPM/line)

Flow max (GPM/line)

Step

Nozzle Pressure (NP) (psi)

Typical: Fog 100 / Smooth bore 50 / Master stream 80–100

Number of attack lines

Elevation gain (+ft) / loss (-ft)

Uses 0.434 psi/ft.

Supply diameter

Supply length (ft)

Attack diameter

Attack length (ft)

Wye / Gated Wye (10)

Standpipe / FDC friction (25)

Master stream device (10)

Other minor appliance (5)

Custom appliance loss (psi)

Note

Training estimate only. SOP/SOG, nozzle specs, hose condition, appliances, and standpipe characteristics can affect actual pressures.
