Excerpt from The Journal of the Franklin Institute, Vol. 99: Devoted to Science and the Mechanic Arts, January to June, 1875
It is estimated that the explosive power of nitroglycerin is equal to ten times that of gunpowder, and that half a kilogram (11 pounds) would lift from the ground and project a weight of kilograms. The heat evolved in the reaction is about calories for each kilogram. This same kilogram of nitroglycerin, exploding in a closed space having a volume of one liter, develops a theoretical pressure of atmospheres, a temperature of degrees, and a quantity of heat equal to calories.
One liter of nitroglycerin weighs kilograms. In exploding in a space completely filled with it, as happens in a blast-hole in mining operations, or when operating under water, this substance develops a pressure of atmospheres, a pressure eight to ten times that produced by the same volume of gunpowder.
