Question
n an experiment 4.5 kg of a fuel was completely burnt . The heat produced wasmeasured to be 180,000 KJ . Calculate the calorific value of the fuel
Solution
The calorific value of a fuel is the amount of heat energy produced on complete combustion of a given mass of that fuel. It is usually measured in units of energy per mass of the fuel, such as kilojoules per kilogram (kJ/kg).
Here's how to calculate it:
Step 1: Identify the amount of fuel burnt and the heat produced. In this case, 4.5 kg of fuel was burnt, producing 180,000 kJ of heat.
Step 2: Use the formula for calorific value, which is:
Calorific Value = Heat Produced / Mass of Fuel Burnt
Step 3: Substitute the given values into the formula:
Calorific Value = 180,000 kJ / 4.5 kg
Step 4: Perform the calculation:
Calorific Value = 40,000 kJ/kg
So, the calorific value of the fuel is 40,000 kJ/kg.
