**Transcription and Explanation for Educational Website** --- **Instructional Text:** 2. Use Routh Array to check the stability of the process. **Diagram Description:** The diagram illustrates a liquid-level control system featuring a pump in the exit line. Key components of the system include: - **q1 and q2:** These are input flows into the tank. - **h:** Represents the height of the liquid level in the tank. - **LT (Level Transmitter):** Measures the liquid level, sending data to the controller. - **hm:** Represents the measurement signal from the level transmitter. - **LC (Level Controller):** Receives the signal from the transmitter and processes it. - **p:** Represents the controller’s output pressure signal. - **q3:** The output flow from the tank after being controlled by the valve. - **Pump:** Facilitates the movement of liquid through the exit line. - **Valve:** Controls the flow rate of q3 based on the controller’s signal. **Figure Caption:** Figure 11.22 Liquid-level control system with pump in exit line. --- This setup is typically used in process control to maintain a desired liquid level by adjusting the output flow using a feedback loop that incorporates sensing, control, and actuation components.
