What is a high explosion?
: an explosive (such as TNT) that generates gas with extreme rapidity and has a shattering effect.
What are three types of high explosives?
1. Introduction
- blasting and bulk explosives (explosives used for commercial blasting applications or for their manufacture);
- perforating explosives (intended for use in the oil and gas well industry);
- special-application explosives (high explosives used for other applications, including primary explosives).
What are the two classes of high explosives What are the differences between the two classes?
Detonating explosives, such as TNT and dynamite, are characterized by extremely rapid decomposition and development of high pressure, whereas deflagrating explosives, such as black and smokeless powders, involve merely fast burning and produce relatively low pressures.
What are the characteristics of a low explosive?
Low Explosives: Low explosives deflagrate rather than detonate. Their reaction velocities are 2000 to less than 3000 feet per second. Black powder is a good example. These materials normally have little water resistance, are highly flammable, sensitive to a No.
What are the effects of high explosive?
High explosives are able to react at linear rates greater than the speed of sound, while low “explosives” react at subsonic rates. (Note: the speed of sound here refers to the speed of sound IN THE REACTING MATERIAL, not in air.) This is a direct consequence of the chemical/composition differences I outlined above.
What is the difference between high and low level clouds?
The main difference between high and low clouds is that the high clouds are colder. This means that they radiate less energy into space than the lower, warmer clouds. Therefore, high clouds work to “trap” more energy than the low clouds. High clouds are not good at reflecting shortwaves.
What is a low order explosive?
A low explosive is a material that has an explosion velocity of less than 1000 m/s. A low order explosion describes an explosive event where the blast pressure front moves slowly, displacing or heaving (rather than shattering) objects in its path.
What is the difference between high and low viscosity?
The difference between high and low viscosity is the thickness of the material being measured. Low viscosity refers to substances that are thin, such as water, while high viscosity substances are thick.
