Question

In an experiment 4.5 kg of a fuel was completely burnt. The heat produced was measured to be 180,000 kJ. Calculate the calorific value of the fuel ???​

Answer 1

Answer:

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.

Answer 2

Answer:

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.
