What will be the cost impact If the same recipe is prepared using three different fuels ?

To find this we need to observe or find out following things during our practical –

Time taken for cooking a recipe Quantity of fuel consumed Quantity of food (recipe) cooked. Total Cost of each fuel which is consumed

CALORIFIC VALUE OF FUEL

Definition of the calorific value : It can be defined as the amount of heat liberated inKcal for the complete combustion of 1 Kg of fuel.

Calculation of Calorific values to cook “Khichadi” using different fuels ?

Name of the Fuel Fuel consumed * Calorific values = Calories used for preparing . “Khichadi”

1)Wood 1.9 Kg * 3500 = 6650 Kcal

2)Kerosene 0.200 ml * 10000 = 2000 Kcal

3)Gas 0.200 gm * 8600 = 1720 Kcal

Calorific value efficiency

Wood - LowCooking gas - High Kerosene – Medium

Learning : It is observed that because of low calorific efficiency wood quantity got highly consumed compared to cooking gas and kerosene
