Q 2: Two sources of Fuel, Fuel 1 and Fuel 2 are combined in a ratio of 4 kg of Fuel 1 for every 1 kg of Fuel 2. The compositions of Fuel 1 and Fuel 2 are shown below Fuel 1 Mol% Fuel 2 Mol% CH 80 CH, 95 CAH 15 CH 0 5 N2 5 Total 100 Total 100 N₂ (a) Calculate the molar composition of the combined stream [5 marks] (b) Calculate the mass composition of the combined stream [5 marks] (c) If the combined stream is burned in air to completion with just the theoretical stoichiometric oxygen requirement (no excess air), Calculate the exhaust gas composition [10 marks]. Useful Data: Component M. (Relative Molecular Mass) C (carbon) 12 H (hydrogen) 1 O (Oxygen) 16 02 (molecular oxygen) 32 N2 (molecular nitrogen) 28 Air 28.84 Air may be considered as 21% oxygen and 79% nitrogen on a volumetric basis (mole).
