A liquid adhesive, which is used to make laminated boards, consists of a polymer dissolved in a solvent. The amount of polymer in the solution has to be carefully controlled for this application. When the supplier of the adhesive receives an order for 3000 kg of an adhesive solution containing 13 wt% polymer, all it has in hand is (1) 500 kg of a 10 wt% solution, (2) a very large quantity of a 20 wt% solution, and (3) pure solvent. Draw and label a flowchart of this process and do the degree-of-freedom analysis. Calculate the mass of each of the three stocks that must be blended together to fill the order. Use all of the 10 wt% solution.

Question
A liquid adhesive, which is used to make laminated boards, consists of a polymer dissolved in
a solvent. The amount of polymer in the solution has to be carefully controlled for this
application. When the supplier of the adhesive receives an order for 3000 kg of an adhesive
solution containing 13 wt% polymer, all it has in hand is (1) 500 kg of a 10 wt% solution, (2)
a very large quantity of a 20 wt% solution, and (3) pure solvent. Draw and label a flowchart
of this process and do the degree-of-freedom analysis. Calculate the mass of each of the three
stocks that must be blended together to fill the order. Use all of the 10 wt% solution.
