Question: problem 5 10 marks a gas mixture containing 25 wt...

Question details

Problem 5 [10 marks] A gas mixture containing 25 wt% carbon dioxide (CO2) and 75 wt% methane (CH4) flows through a pipe with an internal diameter of 75 mm at a velocity of 25 m/s. Molar mass of CO2 = 44.01 g/mol Molar mass of CH4 -16.04 g/mol a) Draw a flow chart for this proces b) Calculate the volumetric flow rate of the gas in m/s. c) If the density of the gas in 6.2 kg/m3, what is the mass flow rate of the gas in kg/s? d) Calculate the mole fractions of the two gases in the mixture. e) Determine the fraction of CO2 that would have to be removed from the gas to yield a gas containing 10 mol% CO2.
