Question
An aqueous solution of sodium hydroxide contains 30% NaOH by mass. You are required to dilute the aqueous solution to only 8% NaOH by diluting the 30% NaOH solution with a stream of pure water. The 30% NaOH stream operates at atmospheric pressure. The temperature of the process remains constant at 65 °C. Determine the mass flow of pure water needed for the dilution process using manual calculation a
