How to Calculate Mass or Volume of Fuel from Energy Generated

In summary, to calculate the mass or volume of fuel from energy generated, the equation E=mc² can be used. The units of measurement used should be consistent and may include kilograms, joules, liters, or cubic meters depending on the situation. It is also important to consider factors such as energy conversion efficiency, energy losses, and energy density of the fuel. This calculation can be used for any type of fuel, but the results may vary depending on the energy density of the fuel being used.

I have a value for energy output from the engine, like e.g. 10 kJ. I now need to calculate the mass/volume of fuel (diesel is used as fuel) to generate the above energy output from the engine if the engine is running at a speed of 1200 rpm and the specific fuel consumption (if needed at all) is 200 g/kWh.

Can someone provide me with the equations/calculation to do the above?

Can't you convert kWh to kJ?
 

1. How do you calculate the mass of fuel from energy generated?

To calculate the mass of fuel from energy generated, you will need to use the equation E=mc², where E represents the energy generated, m represents the mass of fuel, and c represents the speed of light. Simply rearrange the equation to solve for m, and plug in the known values to calculate the mass of fuel.

2. What units of measurement should be used when calculating mass or volume of fuel from energy generated?

The units of measurement used will depend on the specific situation, but typically mass is measured in kilograms (kg) and energy is measured in joules (J). Volume can be measured in liters (L) or cubic meters (m³). It is important to ensure that all units are consistent in order to get an accurate calculation.

3. Can you calculate the volume of fuel from energy generated?

Yes, it is possible to calculate the volume of fuel from energy generated. You can use the equation E=mc² to solve for the volume of fuel, by rearranging the equation to solve for V (volume). However, keep in mind that the volume of fuel will vary depending on the density of the fuel being used.

4. Are there any other factors that need to be considered when calculating mass or volume of fuel from energy generated?

Yes, there are a few factors that should be taken into consideration when calculating mass or volume of fuel from energy generated. These include the efficiency of the energy conversion process, any energy losses during transportation or storage, and the energy density of the fuel being used. These factors can affect the accuracy of the calculation.

5. Can you use this calculation for any type of fuel?

The equation E=mc² can be used to calculate the mass or volume of fuel from energy generated for any type of fuel, as long as the appropriate units are used and all relevant factors are taken into consideration. However, keep in mind that the energy density of different fuels may vary, so the results may not be the same for all types of fuel.
