45 MJ/kg.
Table 1: The energy density(MJ/kg) of a variety of different fuels.
Fuel energy density.
| Fuel | Energy density |
|---|---|
| Crude oil | 44 MJ/kg |
| Diesel | 45 MJ/kg |
| Gasoline | 46 MJ/kg |
| Natural gas | 55 MJ/kg |
What fuel has the highest energy density?
hydrogen
The highest energy density fuel is hydrogen, which is also the simplest chemical component in existence. Gasoline, which is derived from refining crude oil, contains much more energy than coal (twice the lower grade bituminous) or wood (three times).
What is the energy content of diesel?
Heating fuels and their energy content.
| Energy Source | Unit | Energy Content (Btu) |
|---|---|---|
| Diesel Fuel | 1 Gallon | 139000 |
| Gasoline | 1 Gallon | 124000 |
| Natural Gas | 1 Cubic Foot (cu.ft.) | 950 – 1150 |
| Heating Oil | 1 Gallon | 139000 |
Is diesel more energy dense?
Both diesel and gasoline have about the same energy density; but because diesel has a higher mass density than gasoline, the same volume of diesel has more energy than gasoline.
What is the density of diesel fuel?
about 0.85 kg/l
2.3.
The density of petroleum diesel is about 0.85 kg/l – about 15–20% higher than the density of gasoline, which has a density of approximately 0.70–0.75 kg/l.
How much energy is in a Litre of diesel?
One litre of diesel fuel (auto) has an energy content of approximately 38 MJ – which approximates to 10 kWh (using a ballpark figure) but the efficiency of conversion into kinetic energy is only about 30% – that is better than petrol which is typically 25% depending on the design.
Which fuel has a higher energy content gasoline or diesel?
1 gallon of gasoline has 97%–100% of the energy in 1 GGE. Standard fuel is 90% gasoline, 10% ethanol. 1 gallon of diesel has 113% of the energy in 1 GGE due to the higher energy density of diesel fuel.
What is fuel energy density?
In energy storage and fuels
In energy storage applications the energy density relates the energy in an energy store to the volume of the storage facility, e.g. the fuel tank. The higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume.
How do you find energy density?
Energy density is equal to 1/2*C*V2/weight, where C is the capacitance you computed and V should be your nominal voltage (i.e 2.7 V).
Why does diesel have a high density?
Density depends on two things: weight and volume. A molecule of diesel fuel is heavier than a water molecule, but it’s also much bigger, and the molecules don’t pack together as tightly.
Is diesel energy renewable?
Renewable Diesel — Petroleum Diesel’s Low Carbon Twin
Renewable diesel is made from the same renewable resources as biodiesel but uses a different production process. The result is a renewable fuel that is chemically identical to petroleum diesel and meets the same ASTM specification.
Why does diesel have more energy than biodiesel?
The energy density of biodiesel is between 8 and 10 percent lower than low-sulfur diesel. The difference is even greater between biofuel and regular diesel. Because biodiesel has a low energy density, that means more diesel is necessary to move a vehicle a given distance.
How do you find the density of a diesel?
Use the calculator to divide the fluid weight, found in Step 3, by the volume from Step 2. For example, if you poured 16 ml of fluid in the cylinder, you will use 16 ml. If the total weight of the fluid is 16 grams, the calculation would be 16 g / 16 ml. This would give you a density of 1 g/ml.
What is the volatility of diesel fuel?
Solution(By Examveda Team)
Volatility of diesel fuel oil is Indicated by 90% distillation temperature, i.e., when 90% of sample oil has distilled off. Volatility refers to how easily a fuel vaporizes. It affects how easily you can start your car, warm it up, and how well it runs.
What is the gravity of diesel?
0.82 – 0.95
Specific Gravity Resource
| Liquid | SG @ 60°F / 15.6°C |
|---|---|
| Diesel Fuel Oils 20 | 0.82 – 0.95 |
| Ethylene Glycol | 1.125 |
| Gasoline | 0.68 – 0.74 |
| Kerosene | 0.78 – 0.82 |
How do you convert diesel to kWh?
1 wildly dancing human can produce 400 watt of thermal energy.
Energy content of some fuels.
| 1 kilogram of dry wood | 5,3 kwh | 19,0 mJ |
|---|---|---|
| 1 litre of petrol | 9,1 kwh | 32,6 mJ |
| 1 litre of diesel-oil | 10,0 kwh | 35,9 mJ |
| 1 kilogram of hydrogen | 33,6 kwh | 120,8 mJ |
| 1 kilogram of Uranium 235 | 22,2 million kwh | 80,0 million mJ |
How do you calculate diesel per kWh?
You can ESTIMATE the fuel consumption by multiplying the energy out (kWh) by 0.27 to get litres consumed. If it is a very small diesel (under 10 kW) then maybe closer to 0.3 litres per kWh and if it is a modern, high-speed, diesel over 900 kW then closer to 0.26 litres per kWh.
What is the energy density of coal?
24 Mega Joules /kg
Energy Density of Coal is 24 Mega Joules /kg , which is equal to approximately 6.7 Kilowatt-hours/Kg.
What is the energy content of diesel MJ kg?
42-46 MJ/kg
Heat Values of Various Fuels
| Heat value | |
|---|---|
| Petrol/gasoline | 44-46 MJ/kg |
| Diesel fuel | 42-46 MJ/kg |
| Crude oil | 42-47 MJ/kg |
| Liquefied petroleum gas (LPG) | 46-51 MJ/kg |
What is the energy density of ammonia?
22.5 MJ/kg
The energy density of ammonia is 22.5 MJ/kg at HHV, which is about half of that for typical hydrocarbon fuels but higher than metal hydrides (Zamfirescu and Dincer, 2008; Züttel et al., 2010).
What is high energy density?
High energy density (HED) science is the study of systems of matter and radiation at high temperatures (typically millions of degrees) and pressures (over a million atmospheres).
