How much energy is in a litre of petrol?
To put how small a joule is into perspective, a liter of gasoline has 31,536,000 joules of energy in it. A kilowatt-hour is equal to 3,600,000 joules.
How many kWh is a litre of petrol?
100,000 BTU, 105,500 joules, or 29.3 kWh….
| Fuel | Petrol |
|---|---|
| Unit of supply | kg litre |
| Energy (kWh per unit) | 13.1 9.6 |
| CO2 (kg per kWh) | 0.24 |
| Notes | Petrol weighs 0.73 kg per litre |
What is the calorific value of petrol?
The calorific value of food indicates the total amount of energy, a human body could generate during its metabolism which is expressed in Kilojoules per 100 grams or 100 ml….Calorific Value of Fuel.
| Fuel | Calorific Value Of Fuel( Approximately) |
|---|---|
| kerosene | 45000 |
| Petrol | 45000 |
| Methane | 50000 |
| LPG | 55000 |
How many KW is a litre of diesel?
10 kWh
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.
How do you calculate energy content?
The equation for calculating the energy content of a food source via calorimetry is as follows: Energy (joules) = Mass of water (g) × 4.2 (J/gºC) × Temperature increase (ºC)
How much energy does gasoline have per kilogram?
It therefore has units of energy per length cubed or energy per mass. Gasoline has an energy density of about 45 megajoules per kilogram (MJ/kg).
What is the energy content of a barrel of gasoline?
Energy content of fuels. Gasoline contains, on average, 32 MJ /L. Actual energy content varies, by up to 4%, from season to season and from batch to batch. On average, about 19.5 USgal of gasoline are available from a 42 USgal barrel of crude oil (about 46% by volume), varying due to quality of crude and grade of gasoline.
How is the energy content of a fuel determined?
Energy content or calorific value is the same as the heat of combustion, and can be calculated from thermodynamical values, or measured in a suitable apparatus: A known amount of the fuel is burned at constant pressure and under standard conditions (0°C and 1 bar) and the heat released is captured in a known mass of water in a calorimeter.
What’s the content of one liter of diesel?
1 liter diesel = 36.0 MJ 1 metric tonne coal = 32-35 GJ (bituminous/anthracite) = 27.5 GJ (low-bituminous) 1 cubic feet natural gas = 950 Btu 1 cubic meter natural gas = 36.5 MJ
