Use graphical techniques to determine the Second Order Plus Dead Time (SOPDT) parameters for the following dynamics of reboiler duty (Qr"(t) = Q'(t) reboiler = deviation from previous S.S.) and condenser duty (Qc'(t) condenser = deviation from previous S.S.) in response to a step change of the Feed flow rate (AF = + 10 L/min) in a multi-stage tray-type distillation column. That is, solve SOPDT model parameter values for: Qo' (s)/ F'(s) = Gi(s) and Qc'(s)/ F'(s) = G2(s).
