How Gravity Irrigation Works

The video tutorial explores gravity-based irrigation systems, emphasizing the role of water elevation in determining pressure. It covers low and high-pressure irrigation techniques, including the use of sprinklers and drip emitters. The tutorial also explains friction loss in pipes and introduces components like float valves and siphons. Additionally, it discusses rainwater harvesting systems, highlighting the importance of understanding water pressure, flow rates, and system components to effectively design and implement gravity irrigation systems.
