A non-classical example is the CHE 361 Bioreactor project, which also has two states. Review = Cha. 4 pgs 6 1-65 starting with Transfer Functions of Complicated Models. Fig. 4.1 = “additive”, Fig. 4.2 = “multiplicative” relationships for transfer functions Figs 4.3/4.4 for two liquid surge tanks in series. Here we look at a quantitative example of the interacting tank problem. Let the area of tank 1 (A1) be 10 m2and the area for tank 2 (A2) be 4 m2and assume constant density for the liquid. Also let
