Bomb calorimeter A bomb calorimeter is a type of constant-volume calorimeter used in measuring the heat of combustion of a particular reaction. Electrical energy is used to ignite the fuel; as the fuel is burning, it will heat up the surrounding air, which expands and escapes through a tube that leads the air out of the calorimeter.
The higher heating value is experimentally determined in a bomb calorimeter. The combustion of a stoichiometric mixture of fuel and oxidizer (e.g. two moles of hydrogen and one mole of oxygen) in a steel container at 25 °C (77 °F) is initiated by an ignition device and the reactions allowed to complete.
The following list of modern armament manufacturers presents major companies producing modern weapons and munitions for military, paramilitary, government agency and civilian use.
"Solvent bomb" is any Schlenk bomb dedicated to storing solvent. It is the construction of the flask neck which makes a Straus flask unique. A Straus flask (often misspelled "Strauss") is subclass of "bomb" flask originally developed by Kontes Glass Company, [3] commonly used for storing dried and degassed solvents. Straus flasks are sometimes ...
Direct calorimetry of combustion [ edit ] The first determinations of the energy content of food were made by burning a dried sample in a bomb calorimeter and measuring the temperature change in the water surrounding the apparatus, a method known as direct calorimetry .
A reaction calorimeter is a calorimeter that measures the amount of energy released (in exothermic reactions) or absorbed (in endothermic reactions) by a chemical reaction. It does this by measuring the total change in temperature of an exact amount of water in a vessel.
The GBU-57A/B Massive Ordnance Penetrator (MOP) is a precision-guided, 30,000-pound (14,000 kg) "bunker buster" bomb used by the United States Air Force. [2] The GBU-57 (Guided Bomb Unit-57) is substantially larger than the deepest-penetrating bunker busters previously available, the 5,000-pound (2,300 kg) GBU-28 and GBU-37.
Cone calorimeter stage while in use. Note that thermoplastic walls surround the apparatus, providing safe separation between the flame and the scientist. A cone calorimeter is an instrument used to study the behavior of fire in small samples of condensed phase materials.
