In summary, the potential explosive power of the vapor cloud can be expressed as four equivalent fuel-air charges whose initial strengths remain to be determined. 

Determine the initial strengths of the charges. A quick, simple, yet conservative approach to estimating the initial strengths of the four charges expressing the potential explosive power of the vapor cloud follows ... 

Equivalent charges expressing the vapor cloud s potential explosive power are now known, both in scale and in strength. Their corresponding blast effects remain to be determined. 

The fuel-air charge expressing the explosive power of the source of strong blast is assumed to be of strength number 10. 

In the other type of test, the strength of the detonation (explosive power) is determined. Examples of methods for this type of test are the lead block test [139] and the ballistic mortar test [141]. Only the first type of test, which determines the possibility of a detonation, is discussed here.

The power or strength of an explosive is a measure of its ability to do useful work. This is also termed the potential of an explosive and is the total quantity of heat given off by an explosive at constant volume. The volume of gas (V) and heat of explosion (Q) can be calculated independently. The explosive power of an explosive is then obtained on multiplying Q with V that is, (Equation 1.15) ... 

Picric acid is a strong acid, very toxic, soluble in hot water, alcohol, ether, benzene and acetone, and is a fast yellow dye for silk and wool. It attacks common metals, except for aluminium and tin, and produces salts which are very explosive. The explosive power of picric acid is somewhat superior to that of TNT, both with regard to the strength and... 

The explosive power of picric acid is somewhat superior to that of -> TNT, both as regards the strength and the detonation velocity. Picric acid is prepared by dissolving phenol in sulfuric acid and subsequent nitration of the resulting phenoldisulfonic acid with nitric acid or by further nitration of dinitrophenol (prepared from dinitrochlorobenzene). The crude product is purified by washing in water. 

The explosive power of picric acid is somewhat superior to that of -> TNT, both as regards the strength and the detonation velocity Picric... 

Initiating efficiency, sometimes referred to as initiating power, strength, or priming force, is the ability of a primary explosive to initiate detonation in a secondary explosive adjacent to it. It is usually reported as a minimum amount of primary explosive necessary to cause detonation of the adjacent high explosive with 100%... 

Chemical-Process Vessels. Explosion-bonded products are used in the manufacture of process equipment for the chemical, petrochemical, and petroleum industries where the corrosion resistance of an expensive metal is combined with the strength and economy of another metal. AppHcations include explosion cladding of titanium tubesheet to Monel, hot fabrication of an explosion clad to form an elbow for pipes in nuclear power plants, and explosion cladding titanium and steel for use in a vessel intended for terephthaHc acid manufacture.

It has been pointed out that the water present in a slurry explosive must be vaporised during detonation and thus absorbs energy. Although the water vapour increases the total volume of gas produced the nett effect is still a reduction in strength. Many attempts have therefore been made to find a soluble additive which will replace part of the water to give both increased power and sensitivity. One such substance which has found success is ethylene glycol mononitrate. This when pure is explosive, but for...
