Pressure loss, also known as pressure drop, is the decrease in pressure as measured between two points in a flowing fluid system. Pressure drop occurring along the direction of flow in a pipe is caused by fluid friction, both internal in the fluid itself, as well as with the piping surfaces, piping restrictions or sudden changes in the geometry of the flow path.
