About this app
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.
