Consider the two interconnected tanks shown in the following figure, where vi = 3, 12 - 1, 1/12 - 4. V21 = 1, v20 = 4. 12 gavmin 1 oz/gal ' Balmin Q (f) oz salt Q (1) or sall V2Bal/min Tank 1 initially contains 32 gal of water and 25 oz of salt, and Tank 2 initially contains 36 gal of water and 15 oz of salt Water containing 1 oz/gal of salt flows into Tank 1 at a rate of 3 gal/min. The mixture flows from Tank 1 to Tank 2 at a rate of 4 gal/min. Water containing 3 oz/gal of salt also flows into Tank 2 at a rate of I gel/min (from the outside). The mixture drains from Tank 2 at a rate of 5 gal/min, of which some flows back into Tank 1 at a rate of 1 gal/min, while the remainder leaves the system." Let Q1 (1) and Q2(1). respectively, be the amount of salt in each tank at time r. Write down differential equations and initial conditions that model the flow process. Observe that the system of differential equations is nonhomogeneous. Find the values of Oj and Q, for which the system is in equilibrium, that is, does not change with time, Let OF and Of be the equilibrium values. Enter the exact answers. OZ OZ
