Fire Flow Calculator
Result
Fire Flow Calculator Estimate the required fire flow rate (GPM) for a building based on floor area and construction type. — free online calculator.
Formula
- Fire Flow Calculator calculates its result from C, A, Gpm. It uses the formula Q = 18 × C × √(A) GPM (NFF method). Change any input to recalculate the result instantly.
- The main inputs are C, A, Gpm. Enter them in the units and format shown in the calculator.
- Keep measurements and project assumptions consistent before comparing or combining values.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Fire Flow
- C: 2
- A: 3
- Gpm: 4
Using C = 2, A = 3, Gpm = 4, the calculated result is 249.4153162899.
