- A mixture of propane and butane is fed into a furnace where it is mixed with air. The furnace exhaust leaves the furnace at T: = 309 C, Py = 806.0 mmHg and contains only N,,o,,CO,, and H.O. The partial pressure of O, in the exhaust is Po, = 53.12 mmHg, and the partial pressure of Co, in the exhaust is pco, = 64.48 mmHg.
