Functional Block Diagram - Essay Example The control signals and measures are by dashed lines. These latter concepts seemed to be very vague to an individual at this point. With careful consideration of the process flow diagram described in Figure 1–2, where process 1 effluent fluid is to the surge tank where the effluent are directed to process 2.several constraints exist such as the height in this reservoir. In the event the tank overflows, it may pose a serious environmental risk and hazards that may result in negative economic influence (Levin & Ted, pp. 124-178). Below is the stepwise analyzes of the system in a procedural manner. Control Objective: here, the goal is to maintain the height of the tank within certain bounds since too high height will lead to overflow while too little height problems may arise due to the flow of process 2. Typically, specific height will be selected. This desired height is as the set point. In this section the effluent from process 1and, it is channeled through to process 2. It is that an outlet flow rate is considered an input to this kind of set up (Levin & Ted, pp. 167-189). In most cases, the problem is always to identify and the manipulated input and the disturbance input. Output variables: the most considered out variable is the liquid level with assumption t in the measured quantity. These are the actual number of constraints while solving this process. The liquid levels allowed up to a certain maximum level; upon which when exceeded, the tank overflows. There are limitations on the flow rates via the inlet and outlet valves. Since this is a continuous process, that is, there is an inflow via inlet and out flow via outlet of the tank. Safety, economic considerations and environmental factors: This aspect majorly depends on the futures of the fluid. If it is a lethal chemical, then there exist tremendous environmental
