V. The temperature of a CSTR is controlled by an electronic (4 to 20mA ) feedback control system containing (1) a 50 to 300F temperature transmitter, (2) a PI controller with integral time set at 4 minutes and proportional band at 25 , and (3) a control valve with linear trim, air-to-open action, and Cv=20gpm/psi0.5 through which cooling water flows. The pressure drop across the valve is a constant 20 psi. 9) If the steady state controller output, CO, is 10mA, how much cooling water is going through the valve? 10) If a sudden disturbance increases reactor temperature by 10F, what will be the immediate change on the controller output
