The two tank in series process has following transfer functions: G1(s)=Fi(s)h1(s)=p1s+1Kp1G2(s)=F1(s)h2(s)=p2s+1Kp2 a) Find overall transfer function Go(s)=Fi(s)h2(s). b) Find h2(t) for step input in Fi. What can you say about the response. c) Find K, and of the overall transfer function in terms of Kp1,p1,Kp2,p2 Note that: Kp1=R1;p1=A1R1;Kp2=R2;p2;A2R2 and F1(s)=R1h1(s)
