  "term": "Static Head",
  "field": "Environment",
  "definition": "1. When water is not moving, the vertical distance (in feet) from a specific point to the water surface is the static head.\n\n2. Also called piezometric head or elevation head, at a point is the level to which a liquid would rise in a piezometer, or open-ended tube, connected to the liquid at the point of interest. In a fluid that has a free water surface (a surface at atmospheric pressure) the static head at a point below the water surface can be measured as the vertical distance between the point and the free water surface. Static head ( in meters (m)) is defined as the elevation of a point in a fluid relative to some datum (m) plus the fluid pressure at the point ( Newtons (N) / m² ) divided by the specific weight of the fluid ( N / m³ ).",
