Fire Fighting Calculation Suite

Preliminary calculations on user-entered criteria only. Not an approved fire system design and not compliance with any code (NFPA or otherwise); approval must come from a competent authority.

1. 1. Design flow

   Define the design density and assumed area yourself.

   • Basic Flow Calculator

2. 2. Pressure

   Depends on the losses and elevation you enter.

   • Pressure Calculator

3. 3. Pump estimate

   Use the resulting flow and pressure as the selection reference.

   • Fire Pump Estimate

4. 4. Fire water tank

   Set the required duration per your project requirements.

   • Fire Water Tank Estimate

5. Professional report

   Once calculations are saved to your project, build one consolidated report and export it to PDF/Excel.

   Build the report

These tools are estimating aids only. They do not replace review by a competent engineer, authority approval, or verification against the codes and specifications applicable to your project. Each available tool states its formulas, assumptions, units and limitations explicitly, and assumes no code constants or market rates — all design criteria and percentages are user-entered.
