WebPressure loss in straight pipes or ducts are called the major, linear or friction loss. Pressure loss in components like valves, bends, tees and similar are called the minor, dynamic or local loss. Minor loss can be significant compared to major loss. In fact - when a valve is closed or nearly closed - the minor loss is infinite.
