Question

In an experiment,4.5 kg of fuel was burnt completely. The heat produced was measured to be 180,000 KJ .Calculate the calorific value of the fuel.

Answer 1

Dear Student

Ans: 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
