Does jet fuel weight change with temperature?
Does jet fuel weight change with temperature?
The Gulfstream GV study revealed that each 10°F increase in fuel temperature reduced the GV’s fuel capacity by 200 lbs. The variation between -20°C and +50°C, for example, can be almost 1,400 lbs. Using these numbers, a G450’s published capacity of 29,500 lbs (4,370 US Gallons) at 60°F will drop to 28,900 lbs at 90°F.
What is the density of jet a1?
0.804 kg/L
Typical physical properties for Jet A and Jet A-1
| Jet A-1 | Jet A | |
|---|---|---|
| Density at 15 °C (59 °F) | 0.804 kg/L (6.71 lb/US gal) | 0.820 kg/L (6.84 lb/US gal) |
| Specific energy | 43.15 MJ/kg (11.99 kWh/kg) | 43.02 MJ/kg (11.95 kWh/kg) |
| Energy density | 34.7 MJ/L (9.6 kWh/L) | 35.3 MJ/L (9.8 kWh/L) |
Does petrol density increase with temperature?
That’s because gasoline, like all liquids, expands when heated. Gasoline does expand and contract a little depending on its temperature. When gasoline rises from 60 to 75 degrees F, for instance, it increases in volume by 1 percent while the energy content remains the same.
Does temperature affect fuel density?
Since the density of fuel varies greatly depending on temperature, the volume of actual fuel in the tank varies, and therefore the weight varies.
What is the density of gasoline at 20 degrees Celsius?
680 1.319

| 20°C (68°F) 1 atm | Density, ρ | |
|---|---|---|
| Gasoline | 680 | 1.319 |
| Glycerin | 1,260 | 2.445 |
| Kerosene | 804 | 1.560 |

How many Litres is 1 kg of jet fuel?
Thus, one kilogram of Jet A1 will at most range from a volume of 1.333 to 1.176 litres for the S.G. range of 0.75 to 0.85. For an S.G. of 0.79, one kilogram of Jet A1 would be about 1.266 litres.
What density is good for petrol?
| Fuel | Density@15°C – ρ – | Specific Volume – v – |
|---|---|---|
| (kg/m3) | (m3/1000 kg) | |
| Gas oil | 825-900 | 1.1-1.2 |
| Gasoline | 715-780 | 1.3-1.4 |
| Fuel Oil No.13) | 750-850 | 1.2-1.3 |
How does temperature affect petrol?
That’s how it works: Hot day, level goes up because the volume expands. So if a litre (that’s about a quarter of a US gallon – ‘Murica) of petrol (that’s ‘gasoline’ – ‘Murica) heats up by one degrees C (that’s 1.8 degrees F – ‘Murica) the volume expands by one cubic centimetre (that’s 0.034 fluid ounces – ‘Murica).
Does temperature affect fuel volume?
At 60 degrees Fahrenheit, the fuel’s volume stays constant. Here’s what happens if it’s hot or cold outside. If it’s warm outside and over 60 degrees when the fuel is delivered, it will have expanded because of the heat. After the fuel cools down to normal, the volume will shrink.
What is the composition of jet fuel?
Jet fuel is a clear to straw-colored fuel, based on either an unleaded kerosene (Jet A-1), or a naphtha-kerosene blend (Jet B). It is similar to diesel fuel, and can be used in either compression ignition engines or turbine engines. Commercial Jet A fuel had the lowest elemental concentrations, with the exceptions of chromium, lead, and titanium.
What is the classification of jet fuel?
Jet fuel, aviation turbine fuel (ATF), or avtur, is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is colorless to straw-colored in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet A-1, which are produced to a standardized international specification.
What is the density of jet fuel?
Primarily, high energy density is a must. Jet A-1 fuel has a minimum energy density of 42.8 MJ/kg, a number that currently can only be achieved by liquid fuels. [1] Furthermore, the extreme range of operating conditions experienced by an aircraft places additional limitations on alternative fuels.
What is the specific gravity of jet fuel?
If the empty weight (i.e., no fuel or passengers) of the jet is 360,000 lb and there are 300 passengers aboard with an average weight of 165 lb, determine how many gallons of jet fuel the jet can hold and still be able to takeoff from sea level with an outside temperature of 39˚F. The specific gravity of jet fuel is 0.804.
