A process consists of five perfectly stirred tanks in Series. The volume in each tank is 30 L, and the volumetric flow rate through the system is 5 L/min. At some particular time, the inlet concentration of a nonreacting species is changed from 0.60 to 0.45 (mass fraction) and held there.
(a) Write an expression for c5 (the concentration leaving the fifth tank) as a function of time.
(b) Using Simulink, determine and plot c1, c2, ..., c5. Compare c at t 30 nun with the corresponding value for the expression in part (a).
