Mass balances on systems, Mechanical Engineering

To make strawberry jam, a two-stage process is used as shown in the figure.  First, crushed strawberries and sugar are mixed in a 45:55 ratio by mass. Then the mixture is heated to evaporate water until the residue contains one-third water by mass. Strawberries contain about 15% solids (S) and 85% water (W) by mass.
