Read the passage from an article ‘Analysis of gas and condensate from tight formations’ published by James Speight, in 2020. Answer the following questions given below.
The calorific value (heat of combustion) gives an indication of the satisfactory combustion of hydrocarbon gases, which depends upon the matching of burner and appliance design with certain gas characteristics. It is the amount of energy generated by the complete combustion of a unit mass of the gas. This property is an indicator of the performance and torque potential of the gas for a defined engine configuration. The heating value of natural gas (or any fuel gas) may be determined experimentally using a calorimeter in which fuel is burned in the presence of air at constant pressure. The products are allowed to cool to the initial temperature and a measurement is made of the energy released during complete combustion.
