What is the detonation velocity of flash powder?
Detonation produces pressure waves of some 25,000 feet per second as compared to the common burn rate of 25 feet per second displayed by gun powder. A larger quantity of flash powder will produce a report if placed loosely in a tube with a diameter between 1/2 and 1 inch.
What is the detonation speed of C4?
Table 3
| No. | Explosive type | EXPLO5 |
|---|---|---|
| Detonation velocity (m·s−1) | ||
| 1 | Comp C4 [21] | 7815 |
| 2 | EPX-1 [20] | 7398 |
| 3 | Semtex 10 [27] | 7370 |
How do you find the velocity of detonation?
The formula is: D = a + bρ (1.1) 2 Page 13 It is suggested that the density be within 0.85 of the TMD for this equation to be accurate within 10% to 15%. One method set forth by Kalmet and Jacobs [9] uses a specific hierarchy for the detonation products to estimate detonation velocity.
How much flash powder is in a M-80?
3 grams
The tubes often hold approximately 2½–3 grams of pyrotechnic flash powder; one source states that an M-80 has at least 3 grams of powder. Some contain up to 5 grams or more.
Is flash powder a high explosive?
[3] In fact, the most recent and comprehensive published research con- cluded that the flash powders that were tested (including the most common flash powder formulation) do not detonate and are not high explosives.
What does C4 stand for in explosive?
Composition C-4
Composition C-4 (comp C4) is a commercial American plastic explosive including 1,3,5-trinitro-1,3,5-triazinane (RDX) as an energetic filler bonded by the softened matrix of polyisobutylene binder [17.
What is a detonation wave?
A detonation is a supersonic combustion wave that consists of a shock wave driven by energy release from closely coupled chemical reactions. These waves travel at many times the speed of sound, often reaching speeds of Mach 5, as in the case of a hydrogen–air fuel mixture.
Can I legally make flash powder?
Under federal law, individuals are permitted to make their own explosives as long as they don’t sell them or intend to use them as a destructive device, Thurman said. “If there’s a guy making flash powder for fireworks, there is no way a law enforcement agency can charge him with possession of explosives.”
