**Diagram Explanation: Water Flow in Sand Filtration System** This educational diagram illustrates a water flow setup in a sand filtration system. The system is designed to determine the direction of water flow through a sandy area and assess whether it flows positively or negatively based on height differences. **Components:** - **Water Inlet and Outlet:** There are two vertical columns connected by a horizontal channel filled with sand. Water enters from the left column and exits through the right column. - **Height Indicators:** - \( h_1 = 33 \, \text{cm} \): Height of water in the left column. - \( h_2 = 27 \, \text{cm} \): Height of water in the right column. - **Sand Area:** The sandy area through which water flows, labeled as "Area A," measures 30 cm in length between two designated positions, \( x_1 \) and \( x_2 \). - **Reference Level:** A reference level marked at \( z = 0 \) at the bottom of both columns to measure water heights. **Objective:** - Determine the direction of water flow through the sand. Since \( h_1 > h_2 \), water will flow from left to right, indicating a "positive" direction due to the height difference, which creates pressure to drive the water through the sand. This setup is a simplified model of processes such as groundwater flow or filtration systems, demonstrating principles of fluid dynamics in an educational context.
