  2. Gurney equations - Wikipedia

    en.wikipedia.org/wiki/Gurney_equations

    Small explosive charges, where the explosive's diameter is not significantly larger than its thickness, have reduced effectiveness as gas and energy are lost to the sides. [ 1 ] This loss is empirically modeled as reducing the effective explosive charge mass C to an effective value C eff which is the volume of explosives contained within a 60 ...

  3. Techno-economic assessment - Wikipedia

    en.wikipedia.org/wiki/Techno-economic_assessment

    Techno-economic assessment or techno-economic analysis (abbreviated TEA) is a method of analyzing the economic performance of an industrial process, product, or service. . The methodology originates from earlier work on combining technical, economic and risk assessments for chemical production processes

  4. Table of explosive detonation velocities - Wikipedia

    en.wikipedia.org/wiki/Table_of_explosive...

    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.

  5. TNT equivalent - Wikipedia

    en.wikipedia.org/wiki/TNT_equivalent

    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.

  6. Oxygen balance - Wikipedia

    en.wikipedia.org/wiki/Oxygen_balance

    An explosive with a negative oxygen balance will lead to incomplete combustion, which commonly produces carbon monoxide, which is a toxic gas. Explosives with negative or positive oxygen balance are commonly mixed with other energetic materials that are either oxygen positive or negative, respectively, to increase the explosive's power.

  7. Net explosive quantity - Wikipedia

    en.wikipedia.org/wiki/Net_explosive_quantity

    The net explosive quantity (NEQ), also known as net explosive content (NEC) or net explosive weight (NEW), of a shipment of munitions, fireworks or similar products is the total mass of the contained explosive substances, without the packaging, casings, bullets etc. [1] It also includes the mass of the TNT-equivalent of all contained energetic substances.

  8. Antimatter weapon - Wikipedia

    en.wikipedia.org/wiki/Antimatter_weapon

    An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current ...

  9. Strength (explosive) - Wikipedia

    en.wikipedia.org/wiki/Strength_(explosive)

    The strength, or potential, of an explosive is the total work that can be performed by the gas resulting from its explosion, when expanded adiabatically from its original volume, until its pressure is reduced to atmospheric pressure and its temperature to 15°C. The potential is therefore the total quantity of heat given off at constant volume ...
