Detonation rate

Detonation Rate. 700Qm/sec at d of 1.5g/cc in an iron pipe 25mm in diameter and a wall thickness of 5mm (Ref 20, p 249) (See also Encycl 2, B280)... [Pg.32]

An exothermic chemical reaction that propagates with such rapidity that the rate of advance of the reaction zone into the unreacted material exceeds the velocity of sound in the unreacted material, that is the advancing reaction zone is preceded by a shock wave. The rate of advance of the reaction zone is termed detonation rate or detonation velocity. When this rate of advance attains such a value that it will continue without diminution thru the unreacted material, it is termed a stable detonation velocity. The exact value of this term is dependent upon a number of factors, principally the chemical and physical properties of the material. When the detonation rate is equal to or greater than the stable detona-... [Pg.217]

Detonation (and Explosion), Energy Relationships in. Under the title "Energy Relationships , C.G. Dunkle treats in the lecture, delivered at Picatinny Arsenal, Dover, NJ on Dec 13, 1955, pp 10-14, the following subjects a) Heat and energy of reaction of expls b) Heats of detonation and explosion c) Alternate deton rates d) Force, power or impetus of expls e) Brisance and f) Detonation pressure...

Cj) Caldirola Paterson Equation of State. Dunkle (Ref 10, p 183), stated that Cook (Ref 2c) found by working backward from experimental detonation rates to Corresponding values of covolume, that for all expls at very high pressures the Covolume is a function of the specific volume only. At these pressures all molecules have the same covolume per unit weight the dependence of a(T,v) on temperature is exceedingly small. The equation of state can be written pV = nRT +a(v)p... [Pg.274]

It is mentioned under "Burning (ot Combustion) and Burning Characteristics of Gases, Vapors and Dusts , described in this Vol, that while burning rate depends to a certain extent on the diameter of pipe in which the gas burns, the detonation rate does not de-(Eq 1) pend on diameter, provided it is sufficiently large...

Influence of inert ingredients on detonation rates of gases is discussed in Ref 2, pp 145-46. Usually they decrease the velocity, but there are cases when they increase it (if added in small amounts), but only slightly. This increase takes place only when the pre-... [Pg.356]

The effects of particle size on detonation rate have been studied by observing the functioning of mixes of various granulations in pressed expl charges, and the influence of cryst size on the props of castings of formulations, such as of Comp B. [Pg.465]

In the Case of Ammonium Picrate, addn of either a small percentage of coarse to fine material or vice versa lowered the detonation rate. Also under the conditions studied, a mixt of 70% coarse 30% fine particles would not propagate detonation... [Pg.465]
