Question

in an experiment 5 kg of fuel produce 275000 J of heat energy calculate thee calorific value of the fuel in kj per kg

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:

=45000 kilojoules

Explanation:

Calorific value of

Petrol=45000 j

If we divide 275000 to 5 kg the result is

=45000 j.

Examples= Petrol, Kerosine, Diesel.
