Question

How much energy will be produced when 450 kg fuel with calorific value of 75kJ/kg is completely burnt.

Answer 1

$\huge\boxed{Answer}$

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.
