Summary

The three steps of the TNT equivalence method: explosive energy from the released fuel, equivalent TNT mass, and scaled distance, followed by reading the overpressure from an ideal blast chart. Based on Iqbal and Salley (2004), pp. 15-9 to 15-11.

Original illustration for TNT equivalence, level 4 Expert.

Source basis: Iqbal and Salley (2004), p. 15-9 (Eq. 15-1, yield range), p. 15-10 (Eq. 15-2), p. 15-11 (Eq. 15-3 and Figure 15-3)
