The Journal of the Franklin Institute, Vol. 99 - Taschenbuch

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.
