Question

a fuel has the calorific value of 40,000 kj/kg. how much fuel will be required for it to produce heat of 180,000 kj​

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.
