Total Mass fraction of Carbon   atoms in the air stream,  Zc,o = 0.0
Total Mass fraction of Hydrogen atoms in the air stream,  Zh,o = 0.0
Total Mass fraction of Oxygen   atoms in the fuel stream, Zo,f = 0.2987
Total Mass fraction of Carbon   atoms in the fuel stream, Zc,f = 0.2241
Total Mass fraction of Hydrogen atoms in the fuel stream, Zh,f = 0.0125
