The detonation velocity values presented here are typically for the highest practical density which maximizes achievable detonation velocity. [ 1 ] The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the ...
Lycopodium powder is a yellow-tan dust-like powder historically used as a flash powder. [1] Today, the principal use of the powder is to create flashes or flames that are large and impressive but relatively easy to manage safely in magic acts and for cinema and theatrical special effects .
Gas explosions can either deflagrate or detonate based on confinement; detonation velocities are generally around 1700 m/s [3] [4] [5] but can be as high as 3000 m/s. [6] Solid explosives often have detonation velocities ranging beyond 4000 m/s to 10300 m/s. Detonation velocity can be measured by the Dautriche method.
As a simple approximate equation, the physical value of is usually very close to 1/3 of the detonation velocity of the explosive material for standard explosives. [1] For a typical set of military explosives, the value of D 2 E {\displaystyle {\frac {D}{\sqrt {2E}}}} ranges from between 2.32 for Tritonal and 3.16 for PAX-29n.
Explosion temperature is 3141 K, energy of explosion is 5612 kJ/kg (or 3400 - 4000 kJ/kg per various sources) and volume of explosion gases at STP is calculated to be 826 L/kg. Loose powder has density close to 0.4 g/cm 3, hence the common detonation velocities are closer to 3000 m/s and P cj is closer to 15 kbar. [8]
M-80s are an American class of large powerful firecrackers, sometimes called salutes. [1] M-80s were originally made in the mid 20th century for the U.S. military to simulate explosives or artillery fire. The "M" is designated by a U.S. military convention for "standard" equipment and "80" is for the 80 grains (5.2 grams) of flash powder within ...
