In an experiment 4.5 kg of a fuel was completely burnt. The heat produced was measured to be 180,000 kJ. Calculate the calorific value of the fuel.
Calorific value is calcualted as
Calorific Value = Heat / KG
Heat produced on burning 4.5 kg of fuel is 180000
Heat produced by 1 kg of fuel is = 180,000 / 4.5 = 40000
Hence the calorific value of fuel is 40000 kJ/kg
