Question

What is the calorific value of a fuel?

Answer 1

Hint: The quantity of heat generated during the burning of a specific amount of a substance, generally a fuel or food, is known as its heating value (or energy value or calorific value).
The total energy produced as heat when a material undergoes full combustion with oxygen under normal conditions is referred to as the calorific value. Typically, a hydrocarbon or other organic molecule reacts with oxygen to produce carbon dioxide and water while also releasing heat. It may be represented in terms of energy per mole of fuel.

Complete answer:
“Calorific value refers to the quantity of heat produced by complete combustion of a unit volume of a substance.” The amount of heat energy present in food or fuel is measured by full combustion of a specific quantity at constant pressure and under normal circumstances. Calorific power is another name for it. The kilojoule per kilogramme, or KJ/Kg, is the unit of calorific value. In the combustion process, water vapour is produced, and the heat should be recovered using particular procedures. It has a high calorific value if the heat contained in the water vapour can be retrieved. If the heat contained in water vapour could not be recovered when the calorific value of the water vapour was low. The calorific value of a fuel or meal determines its efficiency. If the value is high, then the efficiency will be high as well. If the value is low, the efficiency will suffer as well. The efficiency of a product is directly related to its calorific value. The calorific value of food refers to the total amount of energy that a human body can produce during metabolism, which is measured in Kilojoules per 100 grammes or 100 millilitres. Food's calorific value is usually given in kilocalories (kcal).

Note:
It is critical to understand the calorific value of fuel in order to carry out our daily activities. This information aids us in calculating the amount of energy we transfer. This information is required by gas shippers and providers in order to charge gas customers. It also aids in the calculation of gas shippers' and suppliers' transportation costs. To carry out regular activities, the human body requires calories. The body would cease operating and perish if it didn't have enough calories. People could live a healthy lifestyle if they simply consumed a certain number of calories each day. Too much or too little calorie consumption might lead to health issues.
