Summary

Water application rate for flame extinction of plastic slabs against external heat flux, from fitted test correlations. Based on Tewarson (2002), pp. 3-152 to 3-153.

Original illustration for Critical water application rate, level 4 Expert.

Source basis: Tewarson (2002), p. 3-152 (test conditions: 0 to 17 kW/m², 0 to 7.8 g/(m²·s)) and p. 3-153 (Eqs. 134 to 138); the trend is shown in Figure 3-4.55 on p. 3-153: redraw, do not copy
Alt text: Line chart: water needed to extinguish plastic slabs rises from about 2 to 9 g per square metre per second as external heat flux rises to 17 kW/m2.
