1. A gas stream that contains 1.50 mole\% CO2 flows through a pipeline. Twenty (20.0) kilograms of CO per minute is injected into the line. A sample of the gas is drawn from a point in the line 150 meters downstream of the injection point and found to contain 2.3mole%CO2. a) Draw and label a flowchart of this process. b) Estimate the gas flow rate (kmol/min) upstream of the injection point. 2. An experiment on the growth rate of certain organisms requires an environment of humid air enriched in oxygen. Three input streams are fed into an evaporation chamber to produce an output stream with the desired composition. A: Liquid water, fed at a rate of 20.0cm3/min B: Air (21 mole %O2, the balance N2) C: Pure oxygen, with a molar flow rate one-fifth of the molar flow rate of stream B The output gas is analyzed and is found to contain 1.5 mole\% water. Draw and label a flowchart of the process, and calculate all unknown stream variables
