Question

In an experiment $4.5$ kg of a fuel was completely burnt. The heat produced was measured to be $1,80,000$ kJ. Calculate the calorific value of the fuel(in kJ/kg)?

Answer 1

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

Heat produced by 4.5 kg of fuel =180000 kJ.

Heat produced by 1 kg fuel = $\frac{180000}{4.5}$ =40000 kJ/kg.

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