QUESTION 2 a) Consider the grain supply bin as shown in Figure Q2a. The control system is to maintain the flow of grain from the storage bin to provide a constant flow rate on the conveyor. This flow depends on the height of grain in the bin, and hence the vane-type hopper valve must open or close to compensate for the variation. In this case, an actuator operates this valve to control the grain flow rate. The actuator could be a motor to adjust shaft position. Construct functional block diagram of the system in Figure Q2a. Describe the feedback element, controlled variable, manipulated variable and process variable.
