Gas at 30 °C and 1.4 atm is flowing through an irregular duct. To determine the rate of flow of the gas, nitrogen from a tank is steadily added to the gas stream via a mixing point. The flowing gas. just before the mixing point with the pure nitrogen, analyses at 0.5% nitrogen by volume. After the mixing point, the flowing gas analyses at 2.8% nitrogen by volume. As the pure nitrogen flowed from the tank to the mixing point in the duct, it passed through a rotameter which measured the flow rate at 0.18 m³ min 1 and the nitrogen temperature and pressure at that point were 12 °C and 305 kPa prior to entering the mixing point. Assuming an appropriate basis, calculate the flow rate of the gas entering the duct in m³ min1, assuming that the conditions inside the mixing point are the same as the duct.

Question
Gas at 30 °C and 1.4 atm is flowing through an irregular duct. To determine the rate of flow of the gas, nitrogen from a tank is steadily added to the gas stream via a mixing point. The flowing gas, just before the mixing point with the pure nitrogen, analyses
at 0.5% nitrogen by volume. After the mixing point, the flowing gas analyses at 2.8% nitrogen by volume. As the pure nitrogen flowed from the tank to the mixing point in the duct, it passed through a rotameter which measured the flow rate at 0.18
m³-min1 and the nitrogen temperature and pressure at that point were 12 °C and 305 kPa prior to entering the mixing point. Assuming an appropriate basis, calculate the flow rate of the gas entering the duct in m3 min1, assuming that the conditions
inside the mixing point are the same as the duct.
