Master Stream Reach
Reach from nozzle pressure and type.
Example
You enter
- Nozzle type smooth_bore_1_75
- Nozzle pressure (psi) 80
You get
- Typical reach 90 ft
- Base reach (ft) 90
- Nozzle type smooth_bore_1_75
Details, formula, and sources
Reach in feet = horizontal-stream and broken-stream reach by nozzle pressure and tip diameter, from NFPA 1965-published nozzle test data.
NFPA 1965 (Standard for Fire Hose Appliances) by name; NFA training-material reach tables.
