Consider a tank used in certain hydrodynamic experiments. After one experiment the tank contains 200 L of a dye solution with a concentration of 1 g/L. To prepare for the next experiment, the tank is to be rinsed with fresh water flowing in at a rate of 2 L/min, the well-stirred solution flowing out at the same rate. (a) Clearly state the initial value problem (differential equation + initial condition) and its solution as a function of time t. (b) Find the time that will elapse before the concentration of dye in the tank reaches 1% of its original value.
