The dry stack gas of an electrical-generation station boiler has the following Orsat analysis: 15 percent CO2, 15 percent O2, and 1 percent CO. This gas passes through a 10-ft2-cross-section metering duct at a velocity of 26 ft/s at standard atmospheric pressure and 200F. Determine the gas mixtures mass flow rate. The universal gas constant is Ru = 10.73 psiaft3/lbmolR. Use the table containing the molar mass, gas constant, and critical-point properties.
