Question

. If the calorific value of the fuel is 3,000 kJ/kg. Find amount of fuel to be completely burnt to produce 1,80,000 kJ of heat energy?​

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.
