Extracted text: Below shows the process flow chart in a combustion chamber where an entering feed mixture (n;) of propane in air containing 4.03 mole% propane. A separate inlet feed is dedicated for a stream of dilution air prior the chamber inlet to ensure no ignition. Suppose that the flow rate of propane in the entering feed mixture is 150 mol/s, determine the molar rate of flow of the dilution air. Give a complete and traceable solution in the space provided below. Avoid erasures. Follow the notation/variables. n, (mol/s) 0.0403 mol C,H, / mol 0.9597 mol air / mol n, (mol/s) 0.0205 mol C,H, / mol n, (mol air / s) 0.9795 mol air / mol 0.21 mol O, / mol 0.79 mol N2 / mol
