<p>Watermark: Fire Safety Academy logo icon, 70 px, 45 % opacity</p> <p><b>New page</b></p><div>== Summary ==<br /> Pressure history of a far-field blast wave at a fixed point: a shock raises the pressure to its peak, a rarefaction takes it below atmospheric pressure, and the pressure then recovers. Based on Zalosh (2002), pp. 3-418 to 3-419.<br /> <br /> Original illustration for [[TNT equivalence]], level 4 Expert.<br /> <br /> * Source basis: Zalosh (2002), p. 3-419, Figure 3-16.12 (redraw, do not copy) and text on pp. 3-418 to 3-419 (shock, rarefaction, recovery, N wave; impulse for structural response)<br /> * Alt text: Pressure against time at a point far from an explosion: a sudden jump to a peak, a fall below atmospheric pressure, then recovery.<br /> <br /> == Licensing ==<br /> New drawing by Fire Safety Academy. © Fire Safety Academy.</div>
