Fire Flow Calculator

How to Use the Fire Flow Calculator

The Fire Flow Calculator is used to determine the required fire flow rate for fire sprinkler systems based on the building area, occupancy density, and fire demand factor.

1. Enter the building area in square feet.
2. Enter the occupancy density in people per square foot.
3. Enter the fire demand factor in gallons per minute per square foot.
4. Click the "Calculate" button to compute the required fire flow rate.
5. The result will be displayed in gallons per minute (gpm).

Working Principle

The required fire flow rate (Q) is calculated by multiplying the building area (A) by the occupancy density (O) and the fire demand factor (D). The formula used is:

Q = A × O × D

Where:

• Q = Required Fire Flow (gpm)
• A = Building Area (sq ft)
• O = Occupancy Density (people/sq ft)
• D = Fire Demand Factor (gpm/sq ft)
