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.
Total mass of fuel = 4.5 kg
Total heat produced = 180,000 kJ
Therefore,
Heat produce by burning 1 kg of fuel = 180,000 kJ/4.5 kg = 40,000 kJ/kg.
So, calorific value of fuel = 40,000 kJ/kg.
