Unknowns are A,B,V, Cw, Cs, Cwd, E, Gw, Gs, Gwd, Gg, Pwd, Pw,
Ps, Pg. The subscripts (W,WD, S and G) indicate amount of water,
wood, salt, and glue respectively. All together there are 15
unknowns. You can write one independent equation for the divider,
three for the evaporator, four for both mixers, which equals 12
independent equations. The second picture details the other three
independent equations.
Please write all 15 independent equations needed to solve this
flow chart. You do not need to solve for additional
information.
