Q-1: Two tanks are connected in together in the followinf unusual way in Fig E2.3. (a) Develop a model for this system that can be used to find h1, h2, w2 and w3 as functions of time for any given variations in inpput. (b) Perform a degrees of freedom of analysis. Identify all input and output variables Additional infotrmation: - The density of the incoming liquid, , is constant - The cross-sectional areas of the two tanks A1 and A2. - W2 is positive for flow from Tank 1 to Tank 2. - The two valves are linear resistances R2 and R3
