Question

The Calorific Value Of A Fuel Is Expressed In A Unit Called As_____

Answer 1

The calorific value of a fuel:-

• The calorific value of a fuel can be defined as the amount of heat produced during the complete combustion of a given amount of substance at STP.
• The calorific value is called the Calorific power.
• Unit of this calorific value is kilojoules per kilogram or $\mathrm{kJ}{\mathrm{kg}}^{-1}$.
• This calorific value is directly proportional to the efficiency of the fuel.
• That is more the calorific value is more will be the efficiency of the fuel.

Therefore, the calorific value of a fuel is expressed in a unit called kilojoules per kilogram $\mathrm{kJ}{\mathrm{kg}}^{-1}$
