Suppose 285 gallons of a mixture containing 12wt%NaCl (sodium chloride) and 88wt% water (solution density =1.0837g/cm3 ) is mixed with an unknown volume of solution that is 26wt%NaCl and 74 wt\% water (solution density =1.1944g/cm3 ). Complete the questions to determine the volume of the second feed solution required to produce a mixture containing 15wt%NaCl. Label the flow chart of the mixing process. Do not leave any spaces empty. How many unknowns are in the problem statement? number of unknowns: Which independent equations can be written to solve for the volume of the second feed solution? volume balance on the total amount of fluid The sum of the weight fractions of the product solution is equal to 1 . mass balance on water The density of the 12wt%NaCl solution relates the solution mass to volume. volume balance on NaCl volume balance on water mass balance on NaCl The sum of the weight fractions of the 26wt%NaCl solution is equal to 1 . The density of the 26wt%NaCl solution relates the solution mass to volume. The sum of the weight fractions of the 12wt%NaCl solution is equal to 1 .
