The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation pressure. The pressure can be calculated using Chapman-Jouguet theory from the velocity and density.
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
The 9K32 Strela-2 (Russian: Cтрела, lit. 'Arrow'; NATO reporting name SA-7 Grail) is a light-weight, shoulder-fired, surface-to-air missile or MANPADS system. It is designed to target aircraft at low altitudes with passive infrared-homing guidance and destroy them with a high-explosive warhead.
The perforations stabilize the burn rate because as the outside burns inward (thus shrinking the burning surface area) the inside is burning outward (thus increasing the burning surface area, but faster, so as to fill up the increasing volume of barrel presented by the departing projectile).
The video game industry continued to be dominated by Nintendo, Sony, and Microsoft; while indie games became more popular, with Minecraft becoming the best-selling game of all time. Handheld console gaming revenue was overtaken by mobile gaming revenue in 2011. The best-selling book of this decade was Fifty Shades of Grey.
Triple-stack container freight train [312] [313] – In order to ensure new streams of traffic and commodities and to bring about a modal shift, the DFC is undertaking trials for running smaller than usual containers, known as dwarf containers (where the container height is lower by 660 mm than normal containers), in triple-stack formation to ...
