Gravity-fed systems rely on the natural force of gravity to move liquids or materials from one place to another. This method is commonly used in various applications, such as water supply systems, where water flows downhill from a higher elevation to a lower one, ensuring a steady flow without the need for pumps. In agriculture, gravity-fed irrigation systems distribute water to crops by utilizing the slope of the land. This efficient approach minimizes energy costs and reduces the need for mechanical equipment, making it a sustainable choice for farmers looking to optimize their water usage while promoting healthy plant growth.
