Make a block diagram and compute the transfer functions for each block in the diagram. This largely involves the transfer functions of the plant as well as the measuring sensors for Liquid Zone Level Control. Make the most educated assumptions possible.

Design a PID Controller and calculate the Kp, Ki, Kd also. Thank you.

Please finish all the task. Greatly appreciate it.
