Extracted text: Problem 1 A fuel gas is made up of 20% propane and 80% CnH2n-2 where n is a whole number. It is burned with an oxygen-enriched stream containing 50% oxygen and 50% nitrogen. The flue gas analyzed 29.72% CO2, 3.49% CO, 7.17% O2, and 59.62% N2. Determine the following: a) % excess air b) empirical formula of C„Hm+2 c) the rate of air supplied in m/h at 400 K and 350 kPa if the fuel is burned at a rate of 1000 m/h at 300 K and 110 kPa d) the moisture carried by the flue gas in kg/h assuming the above flow rate
