(20) Ode the continuously stmed tank reactor and mixing process shown in the figure below. The reactor has two input steams (and) in which the reaction > Bous. The reaction rate forming component B depends upon the concentration of in the reactor. The prostor strewn from this reactor is then fed into a mixing tank and is blended with a second input stream (2) Busting of parent is desired to control the outlet concentration (1) exiting the mixer Assume that the valves on streams 0 and are in a phone the valve settings do not change in this problem Fot).

Identify with written labels the Small final control element controller output, and set point. Do not combine the controller and sensor transmitter in one piece of hardware but rather draw them as separate pieces of hardware. Also, write in the space provided the mars vanalle manied yamable, and all disturbance variables Specify whether as positive or negative and explain why. For this last part, assume that a proportional controller is being used and that a set point increase occms Explain how the sign of K. affects what the controller directs the final control element to do to try 10 control the PV at the set point, The sign is because () in the space prosaed below the figure from part (a), draw and label a closed loop block diagram for this process identifying all of the sms mentioned in part (a). Specify the units of the variables appearing in the diagram
