Question:
Continuing with the previous exercise, let tank 2 be another tank filled with V2 gallons of water. Assume that the dye solution from tank 1 empties into tank 2 as in Figure 5, mixes instantaneously, and leaves tank 2 at the same rate R. Let c2(t) be the dye concentration in tank 2 at time t.
(a) Explain why c2 satisfies the differential equation
(b) Use the solution to Exercise 43 to solve for c2(t) if V1 = 300, V2 = 200, R = 50, and c0 = 10.
Data From Exercise 43
Tank 1 in Figure 5 is filled with V1 liters of water containing blue dye at an initial concentration of c0 g/L. Water flows into the tank at a rate of R L/min, is mixed instantaneously with the dye solution, and flows out through the bottom at the same rate R. Let c1(t) be the dye concentration in the tank at time t.
