SOLVED: Q1) Consider the control loop shown in Figure 1.Differential pressure (DP)ControllerTankFigure 1What is the chemical process? What are the possible control objectives for this process? What are the controlled variables of the process? What are the disturbances? What are the manipulated variables?

Working Principle of Control Valves A control valve is a mechanical device used to regulate the flow of fluids (liquids, gases, or slurries) within a system. It does so by varying the size of the flow passage, based on signals from a controller, to maintain desired process variables such as pressure, temperature, or flow rate. Below is an explanation of the working principle: --- Components of a Control Valve: 1. Body: Contains the valve components that interact with the fluid. 2. Actuator: Prov
