How do you calculate calorific value of fuel?
Goutel suggested the following formula from calculating the higher calorific value when the percentage proximate analysis of fuel is known. The formula is, cal. value = 343.3 x fixed carbon % + α x % volatile matter kJ/kg. Goutel formula is unreliable for fuels having high percentage in oxygen.
What is the calorific value of fuel?
The heat value of a fuel is the amount of heat released during its combustion. Also referred to as energy or calorific value, heat value is a measure of a fuel’s energy density, and is expressed in energy (joules) per specified amount (e.g. kilograms).
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.
How much energy is in a gallon of gas?
The energy content of a gallon of gasoline is 132,000 Btu and the refinery efficiency is 90 percent. The amount of energy cost per gallon of gasoline produced is equivalent to about 4 kilowatt hours.
Which fuel is the highest calorific value?
hydrogen
Calorific value is nothing but the energy contained in a fuel or food, determined by measuring the heat produced by the complete combustion of a specified quantity of it. This is now usually expressed in joules per kilogram. Hence, hydrogen has the highest calorific value.
How much energy is in a Litre of petrol?
calorific values: diesel: 10.7 kWh/l; jet fuel: 10.4 kWh/l; petrol: 9.7 kWh/l.
How much energy is in a litre of petrol?
One litre of gasoline contains the energy equivalent to 8.9 kWh of electricity.
How much energy is in a gallon of diesel fuel?
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 |
How do you calculate calorific value of glucose?

How do I calculate calories from fat?
To calculate this, divide a food or drink’s calories from fat by total calories (this information is on the product’s food label) and then multiply by 100. For example, if a 300-calorie food has 60 calories from fat, divide 60 by 300 and then multiply by 100.
Which fuel has higher calorific value among given fuels?
8. Which fuel has higher calorific value among given fuels? Explanation: Gasoline also called as petrol, has the highest calorific value. Gasoline is a transparent petroleum derived liquid that is used primarily as a fuel in internal combustion engines.
How many BTU is a gallon of diesel fuel?
1 gallon of diesel fuel or heating oil (with sulfur content less than 15 parts per million) = 137,381 Btu ; 1 gallon of heating oil (with sulfur content at 15 to 500 parts per million) = 138,500 Btu; 1 barrel of residual fuel oil = 6,287,000 Btu; 1 cubic foot of natural gas = 1,037 Btu; 1 gallon of propane = 91,452 Btu
How much fuel is in a barrel of gasoline?
1 metric tonne gasoline = 8.44 barrels = 1342 liter = 42.8 GJ 1 US gallon diesel = 129000 Btu = 136 MJ = 36 MJ/liter 1 liter diesel = 36.0 MJ 1 metric tonne coal = 32-35 GJ (bituminous/anthracite) = 27.5 GJ (low-bituminous)
How much propane is in a cubic foot of natural gas?
1 cubic foot of natural gas = 1,037 Btu 1 gallon of propane = 91,452 Btu 1 short ton (2,000 pounds) of coal (consumed by the electric power sector) = 18,856,000 Btu 1 kilowatthour of electricity = 3,412 Btu
How many MJ in a gallon of gasoline?
1 1 US gallon gasoline = 115000 Btu = 121 MJ = 32 MJ/liter 2 1 boe (barell of oil equivalent) = 42 US gallons = 35 Imperial Gallons = 159 liter = 5.1 GJ = 4.8 million Btu = 1400 kWh 3 1 metric tonne gasoline = 8.44 barrels = 1342 liter = 42.8 GJ 4 1 US gallon diesel = 129000 Btu = 136 MJ = 36 MJ/liter 5 1 liter diesel = 36.0 MJ
