Head Loss
Head Loss is a common term in water supply and plumbing systems that describes how water loses energy as it flows through pipes and equipment. Think of it like traffic slowdown on a highway - just as cars slow down at turns and intersections, water loses some of its flow strength when going through pipes, bends, and valves. Understanding Head Loss is crucial because it helps engineers design systems that ensure water reaches its destination with the right pressure, whether it's for drinking water in buildings or industrial water systems.
