Fuels and Combustion A sample of natural gas containing 80% methane (CH₄) and rest nitrogen (N₂) is burnt with 20% excess air. With 80% of the combustibles producing CO₂ and the reminder going to CO, the Orsat analysis in volume percent is CO₂ : 7.60, CO : 1.90, O₂ : 4.75, N₂ : 85.74 CO₂ : 6.26, CO : 1.56, O₂ : 3.91, H₂O :15.66, N₂ : 72.60 CO₂ : 6.39, CO : 1.60, O₂ : 3.99, H₂O:25.96, N₂:72.06 CO₂ : 7.42, CO : 1.86, O₂ : 4.64, N₂:86.02 CO₂ : 7.60, CO : 1.90, O₂ : 4.75, N₂ : 85.74 CO₂ : 6.26, CO : 1.56, O₂ : 3.91, H₂O :15.66, N₂ : 72.60 CO₂ : 6.39, CO : 1.60, O₂ : 3.99, H₂O:25.96, N₂:72.06 CO₂ : 7.42, CO : 1.86, O₂ : 4.64, N₂:86.02 ANSWER DOWNLOAD EXAMIANS APP
