process control please anwser all questions

6.31 Determine the decay ratio of a second-order process if the overshoot is 0.05 . 6.32 Consider a pressure control loop that exhibits underdamped behavior. The pressure control loop is tuned for 0.10 overshoot, and the time period for oscillations is 1 minute. The control loop is tuned properly so that after the process reaches steady-state operation, there is no noticeable offset between the setpoint and the measured value of the pressure. Develop a second-order transfer function for this closed-loop system assuming that the input is the pressure setpoint and the output is the measured value of the process pressure
