Chose to solve either Exercise 1 or Exercise 2. 2. Exercise ( Option 1 : Application of Modeling connected tanks) [Option 1 : 1 point ]12 tanks are connected in series, interacting case, as shown in figure if the cross-section area of each tank is 12m and all the pipes between them has a radius of 0.75m . Find the final value of the response of the level in tank 12 if a 25-unit-step-change is made in the inlet flow rate to tank 1? show all your work. 91 A2 hi h2 R1 R2 90 Figure 2: Two tanks are connected in series, interacting case 3. Exercise (Option 2. Application of Modeling connected tanks) [1 point ]2 tanks are connected in series, interacting case, as shown in figure if the cross- section area of each tank is 12m2 and all the pipes between them has a radius of 0.75m . Find the instantaneous response of the level in tank 12 if a 25-unit-step-change is made in the inlet flow rate to tank 1? show all your work
