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.

Text Solution

Verified by Experts

Given : Weigth of fuel burnt = 4.5 kg
To find : Calorific value = ?
Formula used :
Calorific value = `(" Amount of heat produced")/("Weight of fuel burnt")`
Calorific value = `(180000)/(5)`
`therefore ` Calorific value = 40,000 Kg/kg
