What is the speed of an explosion?
Gas explosions can either deflagrate or detonate based on confinement; detonation velocities are generally around 1600 m/s to 1800 m/s but can be as high as 3000 m/s.
Solid explosives often have detonation velocities ranging beyond 4000 m/s to 10300 m/s..
What makes an explosion happen so quickly?
Burning very rapidly, explosive material releases concentrated gas that expands quickly to fill the surrounding air space and apply pressure to everything in it. … In real life, movie-type blasts require an explosive like C-4, TNT or gasoline, which cause explosions when they burn and mix with oxygen.
How does an explosion kill you?
Explosive shock waves can cause situations such as body displacement (i.e., people being thrown through the air), dismemberment, internal bleeding and ruptured eardrums. Shock waves produced by explosive events have two distinct components, the positive and negative wave.
What does explosion mean?
an act or instance of exploding; a violent expansion or bursting with noise, as of gunpowder or a boiler (opposed to implosion). the noise itself: The loud explosion woke them. a violent outburst, as of laughter or anger. a sudden, rapid, or great increase: a population explosion.
What is c4 made of?
C-4 is made up of explosives, plastic binder, plasticizer and, usually, marker or taggant chemicals such as 2,3-dimethyl-2,3-dinitrobutane (DMDNB) to help detect the explosive and identify its source.
Is ANFO high explosive?
While many fuels can theoretically be used, the low volatility and cost of diesel make it ideal. ANFO under most conditions is blasting cap–insensitive, so it is classified as a blasting agent and not a high explosive. Ammonium nitrate is widely used as a fertilizer in the agricultural industry.
How much PSI is in a nuclear bomb?
Overpressure ranges from 1 to 50 psi (6.9 to 345 kilopascals) of a 1 kiloton of TNT air burst as a function of burst height.
What chemicals are explosive when mixed?
Pages in category “Explosive chemicals”Acetone peroxide.Acetyl nitrate.Acetylene.Ammonium azide.Ammonium chlorate.Ammonium dichromate.Ammonium dinitramide.Ammonium nitrate.More items…
What causes gas cylinder to explode?
Gas leaks from poor connections, faulty gas regulators and damaged hoses are the most common causes. … The gas leak is rarely from the gas bottle itself and an actual gas cylinder explosion or Propane-LPG tank explosion, resulting from a BBQ fire, would be very unusual.
Is Semtex the same as c4?
There are visual differences between Semtex and other plastic explosives, too: while C-4 is off-white in colour, Semtex is red or brick-orange. The new explosive was widely exported, notably to the government of North Vietnam, which received 14 tons during the Vietnam War.
How is Semtex detonated?
Pentaerythritol tetranitrate, or PETN, is a major ingredient of Semtex and belongs to the same chemical family as nitroglycerin. PETN is relatively stable and is detonated either by heat or a shockwave. … A little more than 100g of PETN could destroy a car, experts say.
What is the most powerful explosive?
One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.
What are the 3 categories of high explosives?
High explosives are divided into three main categories, Primary (or Initiating) High Explosives, Secondary High Explosives, Boosters and Secondary High Explosives, Main Charge. As with many of the terms associated with explosions, there is also other terms that describe combustion explosions, “Deflagration Explosion”.
How many PSI can kill you?
The threshold value for lung damage is 12 psi and fatal effect is 40 psi (Glover, 2002). At a pressure of about 35 kilopascals (5 psi), the human eardrum may rupture. With an overpressure of 100 kPa (14 PSI) almost all eardrums will be ruptured.
What caused Lebanon explosion?
The disaster, which is still under investigation, happened when a fire triggered the detonation of 2,750 tonnes of ammonium nitrate that had been stored unsafely.
What is the most dangerous explosive?
Azidoazide azideLike all azides, it reacts with water to emit explosive, highly toxic hydrogen azide. Azidoazide azide has been called “the most dangerous explosive material in the world.” It is also No. 3 in K. S. Lane’s list “The 10 Most Dangerous Chemicals Known to Man”.
Is it safe to breathe compressed air?
Compressed air gets used across a range of industries to provide respiratory protection. It’s used in applications where the risk of breathing ambient air is too high to mitigate using half or full-face respirators. But it is not safe to breathe the compressed air directly following compression.
What was the biggest explosion ever?
The Messines mines detonation killed more people than any other non-nuclear man-made explosion in history.
What happens to a human body in an explosion?
The main direct, primary effect to humans from an explosion is the sudden increase in pressure that occurs as a blast wave passes. It can cause injury to pressure- sensitive human organs, such as ears and lungs.
How far away can you hear Tannerite?
Tannerite is a powdery substance used for firearms practice. When hit by a high-impact rifle, the explosion can make a large booming noise, similar to a firework going off. Sheriff Main said a previous loud noise investigation his department responded to was near Blanchard and was heard up to 7 miles away.
Why doesn’t sugar explode when we eat it?
So, why doesn’t sugar explode or at least light on fire when we eat it? When we eat sugar, the process is different because it happens within cells in our body and is con- trolled by large molecules called enzymes. … This reaction occurs at a slower rate and the energy is stored, so no explosion occurs.
