Calorific value: The amount of heat energy released on complete combustion of 1 kg of a fuel is called calorific value.
It is expressed in a unit called kilo joule per kg (kJ/kg).
Calorific value = heat produced / weight of fuel used in Kgs
Heat produced = 180000 kJ
Weight of the fuel used in Kgs = 4.5
Calorific value = 180000/ 4.5
= 40000 kJ/kg

Calorific value=heat produced/amount of fuel
=180000/4.5
=40000kj/kg
=180000/4.5
=40000kj/kg
