Summary

Air inflow of a room near or after flashover against the ventilation factor of its opening. Based on Walton and Thomas (2002), p. 3-174.

Original illustration for Vent flow, level 4 Expert.

Source basis: Walton and Thomas (2002), p. 3-174 (Rockett 0.40 to 0.61, Thomas and Heselden 0.5; temperature dependence small above 150 °C)
Alt text: Line chart: air inflow rises in proportion to the ventilation factor; a band between 0.40 and 0.61 times with a central line at 0.5.
