cowdung cakes have low calorific value,what is meant by this statement?
Answers
Cowdung cakes have no low calorific value means that on combustion they yield less energy in the form of KJ/Kg.
Explanation:
When complete combustion of a unit of food or fuel takes place it yields energy, this energy released is termed calorific value.
The calorific value is measured or expressed in KJ/Kg.
The low calorific value fuel releases no heat because the ash or volatile substances escapes in the environment readily.
Bomb calorimeter is used to record the calorific value.
The low ash content is an indicator of low contamination and hence used as fertilizers. Low calorific value of the cow dung makes it a good fertilizer and a good fuel.

Cowdung cakes have low calorific value
Explanation:
- Calorific value is defined as the amount of heat energy produced on complete combustion of 1 kilogram of a fuel.
- It is expressed in a unit called kilo joule per kg. The higher the calorific value of a fuel, the more is its efficiency.

Table below shows calorific value of different fuels:
Fuel Calorific value
Hydrogen 150000
LPG 55000
CNG 50000
Methane 50000
Petrol 45000
Kerosene 45000
Diesel 45000
Biogas 40000
Coal 33000
Wood 22000
Cow dung 8000
- Each kilogram of LPG produces much more heat than one kilogram of wood or coal.
- The calorific value of LPG is the highest among wood, charcoal and LPG.
- In rural areas, cow dung and wood are still used as fuel because these are very cheap and easily available.
