There are N storage tanks of volume V arranged so that when water is  fed into first tank, equal volume of liquid overflows from the first tank to the  second tank and so on. Each tank initially contains zero concentration of  component A and equipped with a perfect stirrer. At time zero, a stream of  concentration ‘Co’ of component ‘A’ is fed into first tank at a volumetric flow  rate ‘q’. Find the resulting concentration in each tank as a function of time.
