Question

In an experiment If fuel is 6.5 kg and heat produced is 280000 kg then what is calorific value

Answer 1

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 = 280000 kJ Weight of the fuel used in Kgs = 6.5   Calorific value     = 280000/ 6.5                            =4307.6  kJ/kg
