The stirred-tank heater system shown in Fig. is controlled by a PI controller The following data apply: psi w, flow rate of liquid through the tanks: 250 lb/min Final Holdup volume of each tank: 10 ft3 Density of liquid: 50 lb/ft3 Final control element: A change of 1 psi from the - Thermocouple controller changes the heat input q by 100 Btu/min. The final control element is linear. The thermocouple used in the process has the following characteristics: The thermocouple when left on a table for some time, is registering the room temperature, 75F. Suddenly, when it is placed in a 400F oil bath. The following data are obtained for the response of the thermocouple. 10 Time, s 0 1 2.5 5 8 15 3000 Thermocouple reading, F 75 107 140 205 244 282 328 385 400 Draw a block diagram of the control system with all the transfer functions derived for the individual blocks. Show in detail such things as units and numerical values of the parameters. From the block diagram, determine the overall transfer function relating the temperature in tank 3 to a change in set point
