How fast is the wind from an explosion?

Gas explosions can either deflagrate or detonate based on confinement; detonation velocities are generally around 1700 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. Detonation velocity can be measured by the Dautriche method.

How fast is the wind from an atomic bomb?

One third of a mile from the bomb blast, the wind speed was thought to be 620 mph which created a pressure of 4,600 lbs per square feet. Such a force would simply flatten most buildings – which is why the post-bomb photographs of Hiroshima show barely any buildings standing.

What is the wind from an explosion called?

The blast wind is the area of low pressure that causes debris and fragments to rush back towards the original explosions. The blast wave can also cause fires or secondary explosions by a combination of the high temperatures that result from detonation and the physical destruction of fuel-containing objects.

What is the speed of an explosion shockwave?

Detonation waves have typical velocities of 6-8 km/s, or equivalently 6-8 nm/ps.

How fast is the fastest explosion?

Detonation This is a supersonic combustion wave. Detonations in gases propagate with velocities that range from 5 to 7 times the speed of sound in the reactants. For hydrocarbon fuels in air, the detonation velocity can be up to 1800 m/s.

How hot is a nuke Shockwave?

Temperatures of a nuclear explosion reach those in the interior of the sun, about 100,000,000° Celsius, and produce a brilliant fireball.

How fast is an explosion?

Gas explosions can either deflagrate or detonate based on confinement; detonation velocities are generally around 1700 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.

How powerful is 1 stick of dynamite?

A standard stick of dynamite contains about 190 grams of explosive and produces approximately one megajoule of energy, which is enough to blast a 12‐inch tree stump from the ground.

Why do you open your mouth during an explosion?

Explosions create waves of increased pressure, followed by negative pressure, which can be extremely damaging to ears and internal organs. Keeping ones mouth open is said to equalize pressure, therefore reducing internal damage.

Is an atomic bomb hotter than the sun?

During the period of peak energy output, a 1-megaton (Mt) nuclear weapon can produce temperatures of about 100 million degrees Celsius at its center, about four to five times that which occurs at the center of the Sun.

What is the mile radius of an atomic bomb?

The heat from a 1 KT detonation could cause 50% mortality, from thermal burns, to individuals within an approximate 0.4 miles (610 m) radius. This radius increases to approximately 1.1 miles (1800 m) for a 10 KT detonation.

How many mile radius does a nuclear bomb have?

The dangerous fallout zone can easily stretch 10 to 20 miles (15 to 30 kilometers) from the detonation depending on explosive yield and weather conditions.

Does an explosion have a fast rate?

All explosions, regardless of their source, are characterized by a large release of energy, the production of gas molecules that expand quickly, and a rapid rate of reaction.

Are explosions faster than light?

No explosion when a particle is traveling faster than light can through some transparent medium. Nothing can travel faster than light in a vacuum. But, light does slow down when moving through matter.

What happens to air during an explosion?

An explosion can be vi- sualized as a “bubble” of highly compressed air that expands until reaching equilibrium with the surrounding air. Explosive detonations create an incident blast wave, characterized by an almost instantaneous rise from atmospheric pressure to a peak overpressure.

Can a bullet set off a stick of dynamite?

Some bomb materials are highly sensitive to impact. If you shoot a gun at a stick of dynamite, for example, there's a good chance you'll set it off.

How much dynamite is equal to a nuke?

The most striking difference between the explosion of an atomic bomb and that of an ordinary T.N.T. bomb is of course in magnitude; as the President announced after the Hiroshima attack, the explosive energy of each of the atomic bombs was equivalent to about 20,000 tons of T.N.T.

What is C4 made of?

C4 was used during the Vietnam War as part of demolition blocks; today, it is commonly used in both military and civilian settings for demolition and flares. C4 is composed of RDX (91%), dioctyl sebacate (5.3%), polyisobutylene (2.1%), and mineral/motor oil (1.6%) [1].

Are explosions supersonic?

Explosions may be supersonic as in the case with detonations using high explosives like Pentaerythritol tetranitrate (PETN) or subsonic and initiated by deflagration (combusting materials via heat transfer) of low explosives like gun powder, as seen in fireworks or Hollywood pyrotechnics.

What is the fastest explosive?

The structures of cubane and octanitrocubane

ONC is a high-velocity explosive and has a detonation velocity of 10,100 m/s. This makes ONC the fastest known explosive (see the table below).

How big of an explosion can a human survive?

The Hidden Dangers of Changes in Pressure

The human body can survive blasts of sudden pressure of 20-40 psi, but it's not the only thing receiving that pressure. The pressure radiates outward from the blast in all directions.

Can you shower after a nuke?

Immediately after you are inside shelter, if you may have been outside after the fallout arrived: Remove your outer layer of contaminated clothing to remove fallout and radiation from your body. Take a shower or wash with soap and water to remove fallout from any skin or hair that was not covered.

Where would a nuke hit the US?

Redlener identified six cities that have the greatest likelihood of being attacked: New York, Chicago, Washington D.C., Los Angeles, San Francisco, and Houston. Only New York, Washington D.C., and Los Angeles' emergency management websites give ways to respond to a radioactive disaster.

Can you survive a nuke 20 miles away?

At a distance of 20-25 miles downwind, a lethal radiation dose (600 rads) would be accumulated by a person who did not find shelter within 25 minutes after the time the fallout began. At a distance of 40-45 miles, a person would have at most 3 hours after the fallout began to find shelter.
