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 - Science

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.

Solution

The calorific value of fuel is the amount of heat produced by the complete combustion of 1 kg of fuel.

Now,

Heat produced by 4.5 kg of fuel = 180000 kJ

Therefore, heat produced by 1 kg of fuel = 180000/4.5 xx 1 KJ/Kg

= 40,000 kJ/kg

Hence, the calorific value of the fuel is 40,000 kJ/kg.
