The temperature of the liquid in a vessel responds as a first-order system to changes in the flow rate of the inlet. Table 1 shows the data obtained after the flow rate of the inlet was increased from 1 to 3ft3/min. a) As a process control engineer, you are required to investigate the process parameters and transfer function via graphical construction. Please use the graph paper attached. (16 marks) b) Discuss why empirical modeling is important besides fundamental modeling in process control. (4 marks) [20 marks] Jadual 1/Table 1
