During an experiment, a fuel was burnt completely to produce 22, 00,000kJ of heat.if calorific value of fuel is 44,000 kJ/Kg, how much fuel is used in this experiment?

​

Answer 1

Answer:

The calorific value of fuel is the amount of heat produced by the complete combustion of 1 kg of fuel.

Heat produced by 4.5 kg of fuel =180000 kJ.

Heat produced by 1 kg fuel =

4.5

180000

=40000 kJ/kg.

Hence, the calorific value of the fuel is 40,000 kJ/kg.
