## What is Fire Flow Pump Chart?

Check a pump-pressure scenario, then turn a measured hose-only flow test into an observed C-factor you can use in PDP Check. Keep flow, hose length, losses, and the final pressure visible for drills or preplans.

Use it to:

- calculate hose friction loss from coefficient, flow, and hose length
- add nozzle pressure, appliance loss, and elevation loss
- run a Hose Test from user-measured hose-only friction loss, flow, and length
- see the observed C-factor, formula, and source label
- backfill that C-factor into PDP Check and share the result sheet

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.
