Work Capacity in Detonation and Explosion

This means that if it is desired to calculate the effective work potential of an explosive, it is necessary to calculate.or assume the water-gas reaction constant of the detonation products behind the reaction zone, calculate the heat liberated by the decomposition reaction at this equilibrium (Qc) and calculate.the pressure developed on the basis of the gaseous products. A simple approximation of this value can be arrived at by multiplying the heat value Qc by the volume of gas formed at the maximum temperature but expressed as volume at standard temperature and pressure (Vc) 

It is to be Qoted that the total effective work capacity of an explosive usually has two resultants — (1) fragmentation and (2) blast effect or the movement of matter. These can be measured separately. As there is no shattering effect in the ballistic pendulum test, this test may be considered to measure total effective work capacity Ref W.H.
