An aqueous solution of sodium hydroxide contains 30% NaOH by mass.  It is desired to produce an 8% NaOH solution by diluting a stream of the 30% solution with a stream of pure water. Calculate the ratios (g H20/g feed solution) and (g product solution/ g feed solution), and determine the feed rates of 30% solution and diluting water needed to produce 100 lbm/min of the 8% solution.
