💧 NFPA 291 Water Supply & Pump Hydraulics Calculator

Status: Active & Ready

Hose Lay & Target Fire Flow (GPM)

Terminal Output // Standard I/O Ready

[Pump Discharge Math] Calculating PDP:
  - Flow Rate (Q): 150 GPM
  - Hose: 200 ft of 1.75-inch (Coefficient C = 15.5)
  - Friction Loss (FL): 69.8 PSI
  - Nozzle Pressure (NP): 50.0 PSI (Smooth Bore / Low-Pressure Fog)
  - Elevation Head (EP): 0.0 PSI
[Target PDP] 120 PSI Pump Discharge Target
[NFPA 291 Hydrant Grade]
  - Static: 65 PSI | Residual: 48 PSI | Pitot: 36 PSI
  - Projected Flow at 20 PSI Residual: 1,640 GPM
  - NFPA Class: Class AA (Blue Bonnet) -> Excellent Industrial Supply
