Question

11. In an experiment 4.5 kg of a fuel was completely burnt. The heat produced
was measured to be 180,000 kJ. Calculate the calorific value of the fuel.​

Answer 1

SOLUTION

The calorific Value of the fuel is the amount of heat produced by the complete combustion of 1 kg of fuel.

Calorific Value= Heat/KG

Heat produced on burning 4.5 kg of fuel is 180000

Therefore,

Heat produced by 1 kg of fuel is

=)180000/4.5 = 40000

Hence the calorific Value of fuel is 40000kj/kg.

hope it helps ☺️⬆️

Answer 2

Answer:

Calorific value = heat produced / weight of fuel used in Kgs

Heat produced = 180000 kJ

Weight of the fuel used in Kgs = 4.5

★ Calorific value = 180000/ 4.5

= 40000 kJ/kg
