C - The mass of the explosive charge M - The mass of the accelerated shell or sheet of material (usually metal). The shell or sheet is often referred to as the flyer, or flyer plate. V or V m - Velocity of accelerated flyer after explosive detonation N - The mass of a tamper shell or sheet on the other side of the explosive charge, if present
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.
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.
A 5% displayed LFL reading for methane, for example, would be equivalent to 5% multiplied by 4.4%, or approximately 0.22% methane by volume at 20 degrees C. Control of the explosion hazard is usually achieved by sufficient natural or mechanical ventilation, to limit the concentration of flammable gases or vapors to a maximum level of 25% of ...
Octaazacubane potential explosive: 22.9 [4] Hydrogen + Oxygen: 13.4 [5] Gasoline + Oxygen –> Derived from Gasoline: 13.3 [citation needed] Dinitroacetylene explosive - computed [citation needed] 9.8: Octanitrocubane explosive: 8.5 [6] 16.9 [7] Tetranitrotetrahedrane explosive - computed [citation needed] 8.3: Heptanitrocubane explosive ...
The idea behind the shock factor is that an explosion close to a ship generates a shock wave that can impart sudden vertical motions to a ship's hull and internal systems. Many of the internal mechanical systems (e.g. engine coupling to prop) require precise alignment in order to operate.
BMI vs. Body Fat. This article was reviewed by Craig Primack, MD, FACP, FAAP, FOMA. We’ll start at the very beginning: Body mass index (BMI) is a measure of someone’s weight compared to their ...
An underwater charge explosion, conducted by the US Navy. An underwater explosion (also known as an UNDEX) is a chemical or nuclear explosion that occurs under the surface of a body of water. While useful in anti-ship and submarine warfare, underwater bombs are not as effective against coastal facilities.
