Molecular weights of the species in the representative octane combustion are 114, 32, 44, and 18 for C 8 H 18, O 2, CO 2, and H 2 O, respectively; therefore one kilogram (2.2 lb) of fuel reacts with 3.51 kilograms (7.7 lb) of oxygen to produce 3.09 kilograms (6.8 lb) of carbon dioxide and 1.42 kilograms (3.1 lb) of water.
Below that temperature, but above the freezing point of 0 °C (32 °F), it expands becoming less dense until it reaches freezing point, reaching a density in its liquid phase of 999.8 kg/m 3 (62.4155 lb/cu ft). Once it freezes and becomes ice, it expands by about 9%, with a density of 917 kg/m 3 (57.25 lb/cu ft).
As there are many units of mass and volume covering many different magnitudes there are a large number of units for mass density in use. The SI unit of kilogram per cubic metre (kg/m 3) and the cgs unit of gram per cubic centimetre (g/cm 3) are probably the most commonly used units for density. One g/cm 3 is equal to 1000 kg/m 3. One cubic ...
The heating value depends on the source of gas that is used and the process that is used to liquefy the gas. The range of heating value can span ±10 to 15 percent. A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. [2] A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.
At lower pressure, the composition of the ethanol-water azeotrope shifts to more ethanol-rich mixtures. [85] The minimum-pressure azeotrope has an ethanol fraction of 100% [85] and a boiling point of 306 K (33 °C), [84] corresponding to a pressure of roughly 70 torr (9.333 kPa). [86]
Transport costs can reach 50¢ per pound ($1.10/kg) or higher in some remote areas during times of inclement weather or rough terrain conditions, if these locations can be reached at all. The cost of delivering a gallon (3.8 L) of milk is about $3.50 in many villages where per capita income can be $20,000 or less.
[N 16] With 18,000 lb (8,165 kg) of internal fuel and an additional 8,000 lb (3,629 kg) in two 600-gallon external tanks, the jet has a ferry range of over 1,600 nmi (1,840 mi; 2,960 km). [142] The aircraft has a refueling boom receptacle centered on its spine and an auxiliary power unit embedded in the left wing root.
