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.
With the informaiton from the completed table, answer the questions in the boxes provided below and check your answers.
The feed rate of the diluting water is: The ratio of g H20/g feed solution is: The ratio of g product solution/ g feed solution is: |
