AMS Mining Research Organisation Chemist Interview Questions and Answers

Calorific value is the amount of heat energy released per unit mass of a substance during complete combustion.

• Calorific value is a measure of the energy content of a fuel.

• It is typically expressed in units of joules per gram (J/g) or kilojoules per kilogram (kJ/kg).

• Calorific value is determined by conducting a calorimetric experiment, where the fuel is burned and the heat released is measured.

• Different fuels have diffe...read more

The wire used for firing in a GCV machine is typically a nichrome wire.

• Nichrome wire is commonly used in GCV machines for its high electrical resistance and ability to withstand high temperatures.

• It is often coiled or shaped into a specific design to provide efficient heating.

• Nichrome wire is also used in other applications such as heating elements in toasters, hair dryers, and electric ovens.
