Bombs typically rupture within 30 seconds to half an hour, dependent largely on the temperature of the air outside the bottle. [1] A dry ice bomb may develop frost on its exterior prior to explosion. [1] After explosion, it appears to have shattered, with the overall shape of the device intact. [1]
If a steam explosion occurs in a confined tank of water due to rapid heating of the water, the pressure wave and rapidly expanding steam can cause severe water hammer. This was the mechanism that, in Idaho, USA, in 1961, caused the SL-1 nuclear reactor vessel to jump over 9 feet (2.7 m) in the air when it was destroyed by a criticality accident ...
A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. [1] Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space.
Hydrophones are used to monitor the change in water pressure as sound waves propagate through the world's oceans. [9] Sound travels through 20 °C water at approximately 1482 meters per second, compared to the 332 m/s speed of sound through air. [10] [11] In the world's oceans, sound travels most efficiently at a depth of approximately 1000 meters.
The risk of lung trauma is very high, as is the danger from any unsecured objects that can become projectiles because of the explosive force, which may be likened to a bomb detonation. Immediately after an explosive decompression, a heavy fog may fill the aircraft cabin as the air cools, raising the relative humidity and causing sudden ...
A thermobaric bomb is a type of explosive that utilizes oxygen from the surrounding air to generate an intense, high-temperature explosion, and in practice the blast wave typically produced by such a weapon is of a significantly longer duration than that produced by a conventional condensed explosive. The fuel-air bomb is one of the best-known ...
A sudden reduction in pressure causes a rapid phase transition from liquid to steam, resulting in an explosion of water and rock debris. [2] During the last Ice Age, many hydrothermal explosions were triggered by the release of pressure as glaciers receded. [3] Other causes are seismic activity, erosion, or hydraulic fracturing. [4]
The original explosion will send out fragments that travel very fast. Debris and sometimes even people can get swept up into a blast wave, causing more injuries such as penetrating wounds, impalement and broken bones. The blast wind is the area of low pressure that causes debris and fragments to rush back towards the original explosions.
