About 60 kg of fuel was completely burnt for an experiment. The amount of heat energy was found to be 1,80,000 kJ. Calculate the calorific value of the fuel.
The calorific value of fuel is the amount of heat produced by the complete combustion of 1 kg of fuel.
Heat produced by 60 kg of fuel =180000 kJ.
Heat produced by 1 kg fuel = 180000\60
=3000 kJ/kg.
Hence, the calorific value of the fuel is 3,000 kJ/kg.
