= - Consider two tanks in series with gravity-driven flow as 25 Fo. shown in the Fig 1a and 1b, called non-interacting and non bon interacting systems respectively. Note that in the first tank F1 = Qihi, and for the second tank, F2 = azh2. hi a. Derive the dynamic balance equation for the two tanks in terms of deviation variables and cast it in the standard Tank 1 F1 form. b. Find the process transfer function for H2(s)/Fo(s). h2 Express the relation between these two variables using -1. block diagrams. c. Assuming the time constants for the two tanks = 1, and process gains = 1, discuss the nature of the response for hz(t), for a step change in the input, Fo. Tank 2 F2
