Explanation:

The heat produced was measured to be 180,000 kJ. Calculate the calorific value of the fuel. 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.

Answer 2

QUESTION:-

In an experiment 2.5kg of a fuel was completely burnt. the heat produced was measured to be 125000kj.calculate the calorific value of the fuel.

Solution :-

Amount of fuel = 2.5 kg

Heat produced = 125000 KJ

Calorific value = $\frac{125000 \times 10}{25} \\ = \frac{25000 \times 2}{5} \\ 5000 \: {kg}$
