Technology
It is a substance that can undergo extremely rapid, self-propagating decomposition with the formation of large volumes of gaseous products and evolution of heat. It is generally prepared in solid form.
What is an explosive?
It is the energy emitted by matter in the form of electromagnetic waves (or photons) because of the changes in the electronic configurations of the atoms or molecules.
What is Radiation?
It is a generic name for powdered materials which have plastic flow when mixed with water or other liquid, but form a solid structure in several hours with varying degrees of strength and bonding properties which continue to improve with age.
What is cement?
When two bodies at different temperatures are brought into contact, heat transfer occurs until both bodies assume the same temperature at the point of contact. Therefore, a fluid and a solid surface will have the same temperature at the point of contact.
What is the no-temperature-jump condition?
The process consists of condensing chloral and chlorobenzene using strong sulphuric acid (100%) or oleum as a catalyst. The reaction takes place at 15-30°C for 5-6 hours. The spent acid is then withdrawn, and the organic layer is water-washed and neutralised with soda-ash. The products are then dried and distilled for chlorobenzene removal and recycling.
What is the process of DDT manufacture?
The ratio of convective to conductive heat transfer across a boundary. The convection and conduction heat flows are parallel to each other and to the surface normal of the boundary surface and are all perpendicular to the mean fluid flow in the simple case.
What is Reynolds Number?
It is defined as the treatment of hydrocarbons at high temperatures to change their molecular weights. The principal purpose is to crack molecules, however larger molecules are also produced simultaneously
What is pyrolysis?
This process of urea production uses mineral oil as a carrier for temperature control and to minimize corrosion problems
What is the pechiney process?
