Consider the series of continuous stirred tanks reactor (CSTR) shown in figure 1. In this system of reactors, product B is produced from reactant A which is consumed in each of the three perfectly mixed reactors by a first order reaction vccurring in the liquid. Q is the rate of heat added to the second tank per unit time. The volume and the density of each tank is assumed constant throughout the system. If F1=h1h2 and F2=h2 and the tank has a constant cross-sectional area A, formulate a model for this system. Figure 1: Series of CSTR
