5. A gas mixture containing 60% NH3, 10% N2, 26% H2, 4% CO2 flows through a pipe of circular cross-section of diameter 2 cm at atmospheric pressure. The velocity of the components are as follows NH3 is 0.04 m.s!, N2 is 0.035 m.s-1, H2 is 0.024 m.s1 and CO2 is 0.020 m.s-1 a) Calculate the mass average velocity (Answer: 0.0362 m.s) b) Calculate the molar average velocity (Answer: 0.0345 m.st) c) Calculate the volume average velocity of the gas mixture (Answer: 0.0345 m.s1)
