The calorific value of a gas of composition CO2 = 20%, H2 = 50%, CH4 = 30%, is y. If the composition of gas is changed to H2 = 50%, CH4 = 30%, CO2 = 10%, N2 = 10%, then the calorific value will be___________________?

Question

Accepted Answer

y. The calorific value depends on the components that burn (CO2, H2, CH4). Since the change only affects inert gases (N2) and reduces CO2 while increasing N2, the overall energy content remains approximately the same.
