How to Calculate Mass or Volume of Fuel from Energy Generated

  1. Mar 10, 2013 #1
    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?
