Abstract
When a pump must deliver a certain amount of liquid to an elevation H e , it must develop a head H that is higher than H e because part of the head developed by the pump is used up by the resistance of the pipelines to flow. This resistance is caused by friction between the liquid and the wetted surfaces of the pipes (or ducts), and by changes in the direction of flow. It is also caused by the changes in the diameter of the pipes and the resistance rendered by the various fittings.
