Consider a tank used in certain hydrodynamic experiments. after one experiment the tank contains 800 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 8 l/min, the well-stirred solution flowing out at the same rate. find the time that will elapse before the concentration of dye in the tank reaches 1% of its original value. (round your answer to one decimal place.)

t = 100 ln 100
Step-by-step explanation:
D(t) : The amount of dye (in g) at time t (in min)
D(0) = 800 L * 1 g/L = 800 g
the change in D is:
