A furnace is burning natural gas (90% by mol methane and thebalance ethane) at 20 degrees C and 1 atm with 25% excess air at150 degrees C and 1.1 atm. The product gases are at 600 degrees Cand 1 atm. 95% of each fuel gas forms CO2 while the balance formsCO. a) What is the ratio of air supply volume to fuel volume? b)What is the composition of the product gas mixture on a mol% basis?c) What is the ratio of exhaust gas volume to fuel volume?
