Readers ask: What Is The Approximate Energy Content Of Gasoline In Kwh/Gallon?

How much energy is stored in a gallon of gasoline?

Refinery efficiency is about 90 percent and the energy content of a gallon of gasoline is about 132,000 Btu. Put that together and you have about 13,000 Btu of energy cost per gallon of gasoline produced, which is equivalent in energy terms to 4 kilowatt hours.

What is the approximate energy content of gasoline?

calorific values: diesel: 10.7 kWh/l; jet fuel: 10.4 kWh/l; petrol: 9.7 kWh/l.

How do you calculate gas per gallon?

To calculate GGE and DGE, the energy content of one gallon of gasoline or diesel is divided by the energy content of the comparison fuel. For example, conventional gasoline has an energy content of 116,090 Btus per gallon, while propane has an energy content of 84,250 Btus per gallon.

What is the weight of a gallon of gasoline?

It seems impossible that a gallon of gasoline, which weighs about 6.3 pounds, could produce 20 pounds of carbon dioxide (CO2) when burned. However, most of the weight of the CO2 doesn’t come from the gasoline itself, but the oxygen in the air.

Does gasoline contain energy?

Gasoline also known as petrol is an energy-dense secondary fuel that can be thought of as an energy currency. It is used to power many heat engines, most importantly it acts as a fuel for a large proportion of cars. Gasoline is essential to running most internal combustion engine cars.

How efficient is a gasoline engine?

Sadly, even with regular car maintenance such as a tune-up or an oil change, today’s gasoline engines are only around 30 to 35 percent efficient, which means roughly 65 cents out of every dollar you spend on gas goes to waste.

What is energy content of fuel?

Energy content is an important property of fuels. This property helps scientists and engineers determine the usefulness of a fuel. Energy content is the amount of heat produced by the burning of 1 gram of a substance, and is measured in joules per gram (J/g).

How many KW is a litre of oil?

In 1 litre of Kerosene, there are 10.35kWh of heat – so each kWh of oil works out at 3.2 pence per kWh. This is marginally cheaper than buying a unit of gas from the mains grid which works out at about 3.8p / kWh.

How many kWh is a litre of diesel?

A general rule of thumb is that a diesel generator will use 0.4 L of diesel per kWh produced. The diesel engine used is essentially an internal combustion engine.

How many kWh are in a litre of kerosene?

A quick Google search will tell you that one litre of kerosene contains circa 10.35 kWh of energy.

How much hydrogen is equal to a gallon of gas?

In a similar way the energy equivalency between gasoline and hydrogen gas can be found. Convert one gallon of gasoline to the GGE in hydrogen. The result is: One gallon of gasoline has about the same energy as one kilogram (1000 grams, which is about 2.2 lbs.) of hydrogen gas.

How is DGE calculated?

To calculate GGE and DGE, the energy content of one gallon of gasoline or diesel is divided by the energy content of the comparison fuel. For example, conventional gasoline has an energy content of 116,090 Btus per gallon, while propane has an energy content of 84,250 Btus per gallon.
