Below is a ternary liquid phase diagram containing propionic acid and water at 70:30 mass ratio is fed to a mixer at 3.181 kg/s with pure cyclohexane as solvent. What is the flow rate of the pure cyclohexane (solvent) in order to attain 30:70 mass ratio of solute and solvent in the extract (solvent-rich) stream?
