Summary

Steady overpressure of a 100 kW fire against leakage area, without heat losses. Based on Stroup et al. (2016), p. 3-36, and Emmons (2002), p. 2-34.

Original illustration for Fire-induced pressure, level 4 Expert.

Source basis: Stroup et al. (2016), p. 3-36 (Equations 3-4 to 3-6); Emmons (2002), p. 2-34 (orifice flow coefficient 0.60); Iqbal and Salley (2004), p. 14-1 and Quintiere (2002a), p. 3-165 (example values); calculation in calc/fire-induced-pressure-2.py
Alt text: Log-log chart: overpressure of a 100 kW fire falls from thousands of pascals at 0.005 m² leakage to a few pascals at 0.2 m².
