relationship between loading condition and the detonation velocity is shown in
Table
5.47
.
The nitroglycerine emulsion exhibits a certain detonation velocity. The deto-
nation velocity of nitroglycerine emulsions with water is listed in Table
5.48
.
The emulsions with a ratio of water to nitroglycerine over 2:1 cannot be
exploded. The detonation reaction of nitroglycerine with low detonation velocity is
done by the following equation.
