Note: The flooding factor (lb/ft³) is useful for quick estimates. Always use the full NFPA 2001 calculation for final design. Temperature significantly affects agent quantity requirements.

Reference

NFPA 2001 Agent Quantity Formula: W = (V / s) × (C / (100 - C)) × altitude correction where: V = net protected volume (ft³) s = specific vapor volume at temp T (ft³/lb) C = design concentration (%) FM-200 s = 1.885 + 0.004503(T - 70) Novec 1230 s = 2.526 + 0.00549(T - 70) Altitude correction = 1 / (1 - 6.87535×10⁻⁶ × alt)^5.2559
