I am confident that you could not properly equal the explosive effect of Tannerite with TNT.
Tannerite is a Low-order explosives (LE). LE’s create a subsonic explosion [below 3,300 feet per second] and lack High Explosive’s over-pressurization wave. Examples of LE include pipe bombs, gunpowder, and most pure petroleum-based bombs such as Molotov cocktails or aircraft improvised as guided missiles.
TNT is a High Explosive. (HE) is a compound or mixture which, when initiated, is capable of sustaining a detonation shockwave to produce a powerful blast effect. A detonation is the powerful explosive effect caused by the propagation of a high-speed shockwave through a high explosive compound or mixture. During the process of detonation, the high explosive is largely decomposed into hot, rapidly expanding gas.
A chemical explosive is a compound or a mixture of compounds which, when subjected to heat, impact, friction, or shock, undergoes very rapid, self-propagating, heat- producing decomposition. This decomposition produces gases that exert tremendous pressures as they expand at the high temperature of the reaction. The work done by an explosive depends primarily on the amount of heat given off during the explosion.
The term detonation indicates that the reaction is moving through the explosive faster than the speed of sound in the unreacted explosive; whereas, deflagration indicates a slower reaction (rapid burning). A high explosive like TNT will detonate; a low explosive like Tannerite will deflagrate.
The confined detonation velocity of commercial explosives varies from 4,000 to 25,000 fps. The detonation velocity of low explosive such as Tannerite or rifle powder is in the 100's of feet per second.
Do you see the order of magnitude difference between the two types of explosives?
In conclusion Zippy, I don’t think it’s realistically possible to confine enough Tannerite in an enclosed space to create a really large explosion. The reason is, that even if you detonated four cornors of your cache at the same instant, the slower deflagration of Tannerite would throw out large masses of unexploded Tannerite without setting it off.
If you want to post other questions on explosives that don’t violate the COC, I will try to answer them.
Cheers!
