Question

3 kg of fuel is completely burnt to produce 15,000 kJ of heat . Calculate the calorific value of the fuel.​

Answer 1

Answer:

40,000 KJ/KG

Explanation:

Total mass of fuel = 4.5 kg

Total heat produced = 180,000 kJ

Heat produced by burning 1 kg of fuel = 180,000 kJ/4.5 kg = 40,000 kJ/kg. So, calorific value of fuel = 40,000 kJ/kg.
