Fire Hose Friction Loss Calculator

Estimate friction loss, elevation pressure, and pump discharge pressure for hose lays.

Segment 1

Segment 2

Segment 3

Pump discharge pressure

169.8 psi

NP 100.0 + FL 69.8 + EP 0.0 + AL 0.0

Elevation uses 0.5 psi per foot; a quick fireground rule is about 5 psi per floor.

Training aid only. Follow department SOPs, pump charts, hydraulics policy, and incident conditions.

How this tool works

Friction loss is C x (Q/100)^2 x (L/100). Add nozzle pressure, elevation pressure, and appliance loss for estimated PDP.

What assumptions should I check?

Department pump charts and SOPs win. This tool is a training aid for quick hydraulic practice.

Can I use this in the field?

Yes. It is built for phone-width screens and recalculates instantly, but it should support, not replace, site measurements, SOPs, code checks, or professional judgment.

Does it send my data anywhere?

No. The math runs in your browser. For tools with saved rows, storage stays on the device unless you export a file.
