2.3 Two tanks are connected together in the following unusual way in Fig. E2.3. נש h2 h1 W2 ☑ Figure E2.3 (a) Develop a model for this system that can be used to find h₁, h₂, w₁, and w₁ as functions of time for any given 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 A₁ and A₂. w, is positive for flow from Tank 1 to Tank 2. The two valves are linear with resistances R₂ and R₁.
