Hey Mate!!
Here is The answer!

The calorific value can be determined using the heat balance. 
Heat given by the fuel is equal to the heat gained by the water.

LHS:Mass of fuel×calorific value.

RHS:mass if water×specific heat ×change in temperature.

Equate LHS and RHS to get the calorific value.

this is to calculate the calorific value!!
