Psi of explosions

WebThe human body can survive blasts of sudden pressure of 20-40 psi, but it’s not the only thing receiving that pressure. The pressure radiates outward from the blast in all directions. When it leaves a vacuum behind it, air from the surrounding atmosphere moves in to fill that vacuum. This means wind. A lot of it. WebMar 2, 2024 · The blast wave moves outward initially at thousands of miles per hour but slows as it spreads. It carries about half the bomb’s explosive energy and is responsible for most of the physical destruction. Normal air pressure is …
