How many pounds of Tannerite equals a stick of dynamite?

two pounds
No more than four ounces should be used at one. “Usually they come in two or four ounce containers you’re pretty safe 100 feet away with those but two pounds you’d have to be about 300 yards probably,” says Carlson. He says two pounds of Tannerite is equivalent to two sticks of dynamite.

How far do pipe bombs reach?

For a pipe bomb, the US Department of Homeland Security recommends a minimum of 21 m (69 ft), and preferred distance of 366 m (1,201 ft).

How fast do explosions travel?

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. Detonation velocity can be measured by the Dautriche method.

How strong is a blast of 1 kg of TNT?

A single kilogram of dynamite can yield overpressure effects measured at more than 1,200 kPa (174 psi) at 1 meter and 280 kPa (40.6 psi) at 2 meters. The blast wave expands in all directions unless reflected or channeled by a structure.

What is standoff distance in welding?

The distance between the tip of the nozzle and workpiece. It is typically equal to the nozzle diameter used.

How much damage can 1 stick of dynamite do?

The force of different varieties may vary 30 to 40 percent, but a properly placed standard stick can blast a 12‐inch tree stump from the ground. Invented by Alfred Nobel in 1866, dynamite has nitroglycerin based in some porous material that is either inert or can itself intensify an explosion.

What does a stick of dynamite weigh?

Dynamite is usually sold in the form of cardboard cylinders about 200 mm (8 in) long and about 32 mm (11⁄4 in) in diameter, with a weight of about 190 grams (1⁄2 troy pound). A stick of dynamite thus produced contains roughly 1 MJ (megajoule) of energy.

How far is a bomb radius?

In a typical air burst, where the blast range is maximized to produce the greatest range of severe damage, i.e. the greatest range that ~10 psi (69 kPa) of pressure is extended over, is a GR/ground range of 0.4 km for 1 kiloton (kt) of TNT yield; 1.9 km for 100 kt; and 8.6 km for 10 megatons (Mt) of TNT.

How fast can a shockwave from an explosion travel?

The initial blast from the explosion will create a shock wave traveling at over 2,000 mph (3218.688 kph). It eventually slows down as the air pressure equalizes.

How fast is a nuke explosion?

The blast wind at sea level may exceed one thousand km/h, or ~300 m/s, approaching the speed of sound in air. The range for blast effects increases with the explosive yield of the weapon and also depends on the burst altitude.

Is C4 more powerful than TNT?

C4 is a composition of an explosive known as RDX, also called cyclonite, and some other binding ingredients. C4 is more powerful than TNT and is quite stable.
