Question

calorific value of a fuel is 17000 kj/kg. how much fuel is required to produce 35000 kj of heat energy?

Answer 1

Explanation:

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.
