Question

e) In an experiments 4.5 kg of a fuel was completely burnt. The heat produce
was measured to be 180,000 kg. 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
