The low specific energy of natural gas even in liquid form compared ... density at 15 °C is 690 kg/m 3 (30.81 MJ/litre). Kerosene type BP Jet ... This extra weight ...
Jet fuel is a mixture of a variety of hydrocarbons. Because the exact composition of jet fuel varies widely based on petroleum source, it is impossible to define jet fuel as a ratio of specific hydrocarbons. Jet fuel is therefore defined as a performance specification rather than a chemical compound. [1]
Biofuels are biomass-derived fuels from plants, animals, or waste; depending on which type of biomass is used, they could lower CO 2 emissions by 20–98% compared to conventional jet fuel. [4] The first test flight using blended biofuel was in 2008, and in 2011, blended fuels with 50% biofuels were allowed on commercial flights.
A travel expert revealed the science of why food and drinks taste different on a plane — and what he chooses to order once the beverage cart comes around.
The amount of fuel burnt (about 45 tons) and carbon dioxide generated by the seven-hour Virgin Atlantic Flight 100 is exactly the same as if normal Jet A1 kerosene had been used.
Specific energy is energy per unit mass, which is used to describe the chemical energy content of a fuel, expressed in SI units as joule per kilogram (J/kg) or equivalent units. [1] Energy density is the amount of chemical energy per unit volume of the fuel, expressed in SI units as joule per litre (J/L) or equivalent units. [2]
