- Another example of a closed system is a bomb calorimeter, a type of constant-volume calorimeter used in measuring the heat of combustion of a particular reaction.
- A pipe was typically used, which retains much of the heat of combustion and offers some protection from wind and moisture which might tend to extinguish the tobacco.
- The carbon acts as a heat sink, keeping a portion of the heat of combustion located in the propellant rather than having it transferred quickly to the motor casing.
- Second it does not provide for the fact that sugars and starch are virtually completely digested and absorbed, and thus provide metabolisable energy equivalent to their heat of combustion.
- Once C v value of the bomb is determined, the bomb is ready to use to calculate heat of combustion of any compounds by ?H c = C v . ?T
- These 1, 1-oligocyclopropanes are stable ( except when exposed to acids ) and have a large heat of combustion with [ 6 ] ivyane exceeding that of cubane.
- Generally speaking, masses of combustible metals do not represent great fire risks because heat is conducted away from hot spots so efficiently that the heat of combustion cannot be maintained.
- The heat of combustion is approximately-418 kJ per mole of O 2 used up in the combustion reaction, and can be estimated from the elemental composition of the fuel.
- For example, the heat of combustion of cyclopropane ( 696 kJ / mol ) is higher than that of propane ( 657 kJ / mol ) for each additional CH 2 unit.
- The heat of combustion of " producer gas " a term used in the United States meaning wood gas produced for use in a combustion engine is rather low compared to other fuels.
- Another useful term is the heat of combustion, which is the energy mostly of the weak double bonds of molecular oxygen released due to a combustion reaction and often applied in the study of fuels.
- Furthermore, as the aluminum consume the oxygen, it liberates hydrogen which functions as a low molecular mass working fluid to translate the heat of combustion ( and subsequently condensation ) into expansion and thrust.
- Taylor reports that producer gas has a lower heat of combustion of 5.7 MJ / kg versus 55.9 MJ / kg for natural gas and 44.1 MJ / kg for gasoline.
- This is a bit more than the heat of combustion of gasoline, but does not consider the other materials that go into a lithium battery and that make lithium batteries many times heavier per unit of energy.
- Without sufficient water to absorb the heat of combustion, the firebox sheets may soften and melt, with the possible result of high-pressure steam being ejected with tremendous force through the firebox and into the locomotive's cab.
- The principle for the measurement of the heat release rate is based on the Huggett's [ 1 ] principle that the gross heat of combustion of any organic material is directly related to the amount of oxygen required for combustion.
- When working with compounds that are not as flammable ( that might nor combust all the way ) one solution would be to mix the compound with some flammable compounds with a known heat of combustion and make a pallet with the mixture.
- Diesel originally proposed a very high compression constant temperature cycle where the heat of compression would exceed the heat of combustion, however after several years of experiments it was realized that the constant temperature cycle would not work in a piston engine.
- It is important to know and understand the flammability, heat of combustion, ignitability, heat release, and smoke production of many materials in order to maintain a safe environment, all of which can be found by using a calorimeter.
- The gross energy ( GE ) of a food, as measured by heats of combustion of the components protein ( GE p ), fat ( GE f ) and carbohydrate ( GE cho ) ( by difference ) in the proximate system.
