What does TDH stand for in irrigation systems?

Explanation:
TDH stands for Total Dynamic Head. It’s the total amount of head a pump must overcome to move water through an irrigation system. This isn’t just a height; it combines three things: static head (the elevation change water must rise), friction losses in pipes and fittings due to flow, and velocity head (the energy needed because water is moving). You add these components to size pumps and determine the required pressure. Minor losses from valves and fittings can be included too. TDH is expressed in feet or meters of water. The other terms aren’t standard ways to describe this pump-required pressure.
