A combustion chamber is used to burn a foed mixture consisting of methane and ethane. The fuel enters the chamber at a temperature of 25C and a pressure of 1atm. Dry air enters the chamber at a temperature of 200C and a pressure of 1 atm. Excess air is used for combustion. Assurne the air to be 21.0 moles O2 and the balance N2. The flue gas exits at a temperature of 8000C and a pressure of 1 atm, Analysis of the flue gas has the following composition in mole percent: 1.39%CO,6.97%CO2,13.37%H2O,5.11%O2 and the batance N2 What is the mole percent of ethane in the fuel mixture? What is the nercentage by which dry air is fed in eccess? eTextbook and Media Attempts: 0 of 3 used
