Question: Determine the Higher Heating Value (HHV) and the Lower Heating Value (LHV) of a biogas consisting of 80 % methane (CH4) and 20 % carbon

Determine the Higher Heating Value (HHV) and the Lower Heating Value (LHV) of a biogas consisting of 80 % methane (CH4) and 20 % carbon dioxide (CO2) by volume. N.B.: The molar masses of C, H2, and O2 are12 kg/kmol, 2 kg/kmol, and 32 kg/kmol. The HHV of methane is 55,530 kJ/kg and its LHV is 50,050 kJ/kg
