105,000KJ of heat is produced on burning 3.5KG of a fuel completely. Calculate the calorific value of the fuel
Calorific value = heat produced by 1 kg of the fuel
So, in our case the calorific value is = 105000/3.5 = 30000 J/kg
On burning completely 2.5 kg of a fuel produces 87500 kJ of heat energy. The Calorific value of the fuel is –
