## What is Fireflow Pump Chart?

Fire Flow Pump Chart is an offline fire flow calculator for pump-operator drills, preplan checks, and classroom study.

Use it to:

- calculate hose friction loss from coefficient, flow, and hose length
- add nozzle pressure, appliance loss, and elevation loss
- estimate pump discharge pressure for a training scenario
- compare how hose length or flow changes affect the final pressure
- share a plain-text result sheet for drills or study review

Why people pay for it:

- fire flow math is repeated often in pump-operator drills and preplans
- the app keeps the pressure inputs visible instead of hiding them in a generic calculator
- works offline with no account, ads, subscription, analytics SDK, or server dependency

Fire Flow Pump Chart is a training and preplan math aid only. It is not incident command software, an emergency response system, a code-compliance tool, or professional firefighting instruction.
