Two tanks are connected together in the following unusual way in Fig. E2.3. Develop a model for this system that can be used to find hj, h2,W2, and w3 as functions of time for any given variations in inputs. 1. The density of the incoming liquid,p, is constant. 2. The cross-sectional areas of the two tanks are A1 and A2. 3. w2 is positive for flow from Tank 1 to Tank 2. 4. The two valves are linear with resistances R2 and R3.
