The calorific value of fuel can be defined as the amount of heat produced by the complete combustion of one unit of any fuel. The unit depends upon the type of fuel, for example, coal is a solid fuel so it is measured in weight units whereas we use volume units for any gaseous or liquid fuel. Therefore, the calorific value for them will be ...
