Two gases flow into separate ducts and merge into a single duct. Gas1 has a density of 1.5 kg/m3 and flows into a duct with an area of 0.25 m2. a. If gas 2 has a density of 0.8 kg/m3 and a volume flow rate of 2.5 m/s, what is the average speed of gas 1? b. What is the speed of gas 2 if the duct it passes through has an area of 0.5 m2 c. What is the mass flow rate of the mixture?
