Question

In an experiment, a fuel was burnt to produce heat of 2,60,000 KJ

and the calorific value is 40,000 KJ/Kg. Calculate the amount of fuel

used.​

Answer 1

40,090 kj

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

In an experiment, a fuel was burnt to produce heat of 2,60,000 KJ

and the calorific value is 40,000 KJ/Kg. Calculate the amount of fuel

used.
