don't copy other solutions, they're wrong

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. 1. What is the value of Kc,Km,Kv along with their units?[3 marks] 2. If the steady state controller output is 10mA. how much cooling water is going through the valve?[4 Marks] 3. If a sudden disturbance increases reactor temperance by 10F. what will be the immediate change on the controller output.[3 Marks]
