Summary

Relative mass flow through a natural roof vent as a function of the ratio of layer to ambient absolute temperature. Above a ratio of 1.3 the flow is within 80 % of its maximum. Based on Cooper (2002b), p. 3-224.

Original vector illustration for Smoke and heat exhaust ventilation, level 2 Intermediate.

Source basis: Cooper (2002b), p. 3-224, Equation 19 and Figure 3-9.3 (redraw, do not copy)
Alt text: Curve of relative vent mass flow against layer-to-ambient temperature ratio, rising steeply to a maximum of 1 at a ratio of 2 and falling slowly after.
