a Question Five The following is a system of CSTR reactors connected in series. It is required to control the changes in input concentration to tank 1 so that the exit concentration from tank 2 is not affected. Given that the volumetric flow rates to both tanks is constant as F = 4 m3/min; the reactor volumes are V = 5 m3, V2 = 80 m, and the reaction rate constant is the same in both tanks as 1.2 min!, i.e., first order kinetics. F FAO V F FAI V2 F FA2 (b) 1.6 Determine: (a) The time constants for tank 1 and tank 2 (4 marks) The system gains for tank 1 and tank 2 (4 marks) (c) Show that the open loop transfer function for the two tanks combined is given by: G(s) (5s + 10)(8 + 10) (4 marks) (d) If the steady state input concentration to tank 1 is disturbed with a step concentration of 5 M, what will be the open loop change in output concentration from tank 2 after 1 min (8 marks) =
