Please explain detailly

A tank process has been operated for a long period of time with the inlet flow rate equal to 0.8 m3/min. After the operator increases the flow rate suddenly by 10%, the liquid level in the tank changes as shown in the table. a) Assuming that the process dynamics can be described by a first order plus dead time model, determine the model parameters by using (i) process reaction curve method (ii) linear regression method. b) Determine PID parameters by using (i) Cohen Coon method (ii) Open-loop Ziegler-Nichols method. Show the calculations and write your results in the table. (Gm=1,Gvv=1)
