A mixture of propane and butane is fed into a furnace where it is mixed with air. The furnace exhaust leaves the furnace at Tz = 337 'C, P3 = 789.0 mmHg and contains only N., 02, CO2, and H,0. The partial pressure of O, in the exhaust i is , 52.00 mmHg, and the partial pressure of Co, in the exhaust is poo, 63.91 mmHg , Furnace 185 26 co HO 0 What is the mole fraction of propane in the fuel stream? mole fraction: mol CH /mol 1 What is the mole fraction of water in the exhaust stream? mol H, O/mol mole fraction: What is the mole fraction of water in the exhaust stream? mol H2O/mol mole fraction: What is the dew point temperature of the exhaust gas?
