Gas at 15°C and 105 kPa is flowing through an irregular duct. To determine the rate of flow of the gas, CO2 from a tank is passed into the gas stream. The gas analyzes 1.2% CO2 by volume before and 3.4% CO2 by volume after the addition. As the CO2 that was injected left the tank, it was passed through a rotameter, and found to flow at the rate of 0.0917 m3/min at 7°C and 131 kPa. What was the rate of lfow of the entering gas in the duct in cubic meters per minute?
