2.3 Two tanks are connected together in the following unusual way in Fig. E23 Lw Figure E2.3 (a) Develop a model for this system that can be used to find ttfnn m for any siven variations in inputs. (b) Perform a degrees of freedom analysis. Identify all input and output variables. Notes The density of the incoming liquid, p, is constant. The cross-sectional areas of the two tanks are A, and A W2 is positive for flow from Tank 1 to Tank 2. The two valves are linear with resistances R2 and R3
