How do you calculate detonation velocity?
Detonation velocity can be measured by the Dautriche method. In essence, this method relies on the time lag between the initiation of two ends of a detonating fuse of a known detonation velocity, inserted radially at two points into the explosive charge at a known distance apart.
What is the detonation velocity of TNT?
6950 m./sec.
The velocity of detonation of T.N.T. rises as the diameter of the cylinder is increased from a ‘boundary diameter’, below which there is no propagation, to a ‘limiting diameter’ at which the velocity reaches a maximum value. In castings of density 1.625 the maximum velocity is 6950 m./sec.
What has the highest detonation velocity?
10,100 m/s
Octanitrocubane has a detonation velocity of 10,100 m/s, making it the fastest known explosive.
What is the velocity of C4?
The detonation velocities range between 9000 and 15,000 feet per second. This product has no water resistance and fair to good fumes, if properly mixed and detonated.
Which of the following explosive material has highest detonation velocity?
For comparison, Semtex 1A, Semtex 10, Formex P1, and Sprängdeg m/46 were studied. It was concluded that PEX-1 has compatible ingredients, it has the highest detonation velocity of all the studied plastic explosives, and its sensitivity is in the same level of the studied plastic explosives except Semtex 1A.
What the most powerful explosive?
PETN. One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.
How fast is a blast wave?
The shock pressure rise, Ps, generally decreases with distance from the explosion center. Eventually the blast wave decays to an acoustic wave traveling at the speed of sound in air (about 738 mph, 330 m/s).
What is the most powerful explosive material?
Which explosive corrodes most metal?
Which explosive corrodes most metal? Explanation: HMTD ( hexamethylene-triperoxide diamine) is an improvised explosives which corrodes most of metal because of the property of extremely sensitive heat, shock and friction also.
What is the difference between a detonation and a deflagration?
A deflagration occurs when a flame front propagates by transferring heat and mass to the unburned air–vapor mixture ahead of the front. A detonation occurs when the flame velocity reaches supersonic speeds above 600 m/s and generally in the 2000–2500 m/s range.
