Question

The heat produced by complete combustion of 5 kg of fuel is 2,50,000 KJ

Answer 1

HEY MATE

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 KgsHeat produced = 180000 kJ Weight of the fuel used in Kgs = 4.5   Calorific value     = 180000/ 4.5                            = 40000 kJ/kg
