Summary

The same opening geometry supports several different estimates with distinct physical meanings. Based on Walton and Thomas (2002), pp. 3-173–3-175, 3-184–3-186.

Original illustration for Ventilation factor, level 3 Advanced.

Source basis: Walton and Thomas (2002), pp. 3-173–3-175, 3-184–3-186.
Alt text: Opening geometry informs air supply and flashover estimates, while actual internal combustion also depends on fuel and energy released outside.
Accuracy notes: Do not equate 1500 times the factor with actual fire power or the flashover threshold.
