Answer :

To calculate the calorific value of fuel 'A', we need to determine how much heat energy is produced per unit mass of the fuel. The calorific value is defined as the amount of heat produced by the complete combustion of a unit mass of fuel.

Given the data:
- Mass of the fuel = 9.5 kg
- Heat produced = 446,500 kJ

The formula to calculate the calorific value is:

[tex]\[ \text{Calorific Value} = \frac{\text{Heat Produced}}{\text{Mass of Fuel}} \][/tex]

Substitute the given values into the formula:

[tex]\[ \text{Calorific Value} = \frac{446,500 \: \text{kJ}}{9.5 \: \text{kg}} \][/tex]

Perform the division:

[tex]\[ \text{Calorific Value} = 47,000 \: \text{kJ/kg} \][/tex]

Therefore, the calorific value of fuel 'A' is [tex]\( 47,000 \: \text{kJ/kg} \)[/tex].
