4. The following three streams are mixed: - Stream 1: 70 mole\% water (W), 25 mole\% methanol (M), 5 mole\% ethanol (E) - Stream 2: 60 mole\% water (W), 30 mole\% methanol (M), 10 mole % ethanol (E) - Stream 3: 80 mole % water (W), 10 mole % methanol (M), 10 mole % ethanol (E) The output stream from the mixer contains 71.5molW/s,19.75molM/s, and 8.75molE/s. a) Draw and label a flowchart for this process, and perform a degree-of-freedom analysis. b) What is the molar flow rate of each of the three streams entering the mixer? Answers: Stream 125mol/s; Stream 230mol/s; Stream 345mol/s
