5) 10 m3/h of n-pentane vapour is mixed with 40 m3/h of nitrogen gas and 40 m3/h of argon, the mixture then flows through a pipe. The pressure gauge on the pipe reads 3 bar (absolute) and the temperature gauge reads 80 C. a) What is the mass flow rate (kg/s) and mass fraction (in %) of each component? b) Determine whether or not the gas is saturated with n-pentane. c) If the gas mixture is cooled at constant pressure at what temperature will the n-pentane start to condense?
