A furnace is fired with natural gas (assume methane). The inlet air and fuel temperatures are 290 K and the pressure is atmospheric. The residence time in the combustor is 0.1 s. Assuming the combustion to be adiabatic, calculate the NO mole fraction at the combustor outlet for combustion at ϕ = 0.85.
