The incoming water has a pollutant concentration of c.t /
Chapter , Problem 45(choose chapter or problem)
The incoming water has a pollutant concentration of c.t / D 10 liters per cubic meter (L/m3). Verify that the graph of x.t / resembles the steadily rising curve in Fig. 1.5.9, which approaches asymptotically the graph of the equilibrium solution x.t / 20 that corresponds to the reservoirs long-term pollutant content. How long does it take the pollutant concentration in the reservoir to reach 10 L/m3?
