What is meant by velocity of detonation?
Explosive velocity, also known as detonation velocity or velocity of detonation (VoD), is the velocity at which the shock wave front travels through a detonated explosive. Explosive velocities are always faster than the local speed of sound in the material.
Is dynamite or TNT stronger?
It’s the small explosion of the blasting cap that is required to cause the nitroglycerin to explode. You may see some explosives labeled “TNT” that look like dynamite. TNT stands for trinitrotoluene, which is also an explosive but quite different from dynamite. Dynamite is actually much more powerful than TNT.
How many megatons of TNT was Hiroshima?
15 kilotons
The explosive effect of each was equal to that of up to a few tens of thousand tonnes of the conventional explosive TNT. On this basis of comparison, the Hiroshima bomb was of about 15 kilotons – that is, of 15 thousand tonnes of TNT equivalent – and that at Nagasaki was of 25 kilotons (ca.
How fast does a stick of dynamite explode?
Already the first blasting experiments gave proof of the extraordinary power of this explosive. The explosion took place in from two to four minutes.
Is an M-80 a quarter stick of dynamite?
Contrary to urban legend, an M-80 that contains 3,000 mg of powder is not equivalent to a quarter-stick of dynamite. Dynamite generally contains a stable nitroglycerin-based high explosive, whereas M-80s or any other kind of firecracker contain a low explosive powder, like flash powder or black powder.
What is PBXN 9 explosive made of?
Plastic Bonded Explosive Description PBXN-9 explosive consists of a mixture of HMX powder bound with a DiisooctylAdipate (DOA) low boiling point plasticizer and a carbonyl-terminated polybutadiene (HYTEMP 4454) polyacrylate elastomer binder. The elasticity of the matrix lowers sensitivity of the bulk material to shock and friction.
What is the rate of detonation of TNT?
For example, under similar conditions of confinement, trinitrotoluene (TNT) and nitroglycerin detonate at rates of 6,800 and 8,400 meters per second, respectively. The degree of confinement will affect these rates somewhat, but not to the same extent as in the low explosives.
What is the speed of detonation wave?
The speed of the detonation wave, or the velocity of detonation, varies considerably in the various explosives, and may vary in a given explosive under different conditions. For example, under similar conditions of confinement, trinitrotoluene (TNT) and nitroglycerin detonate at rates of 6,800 and 8,400 meters per second, respectively.
What is the rate of detonation for low explosives?
For example, under similar conditions of confinement, trinitrotoluene (TNT) and nitroglycerin detonate at rates of 6,800 and 8,400 meters per second, respectively. The degree of confinement will affect these rates somewhat, but not to the same extent as in the low explosives. There are two categories of low explosives, pyrotechnics and propellants.
