Answer:
The calorific value of fuel is the amount of heat produced by the complete combustion of 1 kg of fuel.
Heat produced by 4.5 kg of fuel =180000 kJ.
Heat produced by 1 kg fuel =
4.5
180000
=40000 kJ/kg.
Hence, the calorific value of the fuel is 40,000 kJ/kg.
OR,
The calorific value of fuel is the amount of heat produced by the complete combustion of 1 kg of fuel.
Heat produced by 5 kg of fuel = 200000 kJ.
Heat produced by 1 kg fuel =
Heat/ kg
so = 5 / 200000
=40000 kJ/kg.
Hence, the calorific value of the fuel is 40,000 kJ/kg.
