plot a system with below closedloop control system a sketch

plot a system with below closed-loop control system

a) sketch the root-loci and show all steps

b) plot the Root-Loci with MATLAB

Solution

a). Now assume that TCE reacts with a first order decay constant of 1 hr-1. Calculate the concentration at point A. Assume that the control volume at A and B are both 1 MG. (Answer= 0.279 ppb)

b) Calculate the concentration of the water leaving point B. (Answer= 0.70 ppb)

c) The EPA determined that the water is safe to drink if the concentration is less than 1 ppb. Are you confident that they can drink the water at point C? Name one assumption that you made that you would check before giving your approval.
