WebTo determine the head loss in pipes due to friction. To determine the head loss in pipes due to fittings, sudden expansion & contraction (associated with flow of water through standard fittings used in plumbing installations). LEARNING OUTCOMES. At the end of the lesson, students should be able to: Conduct the determination of head loss in ... WebThe head loss that occurs in the components of a flow path can be correlated to a piping length that would cause an equivalent head loss. Head Loss. Head loss is a measure of the reduction in the total head (sum of elevation head, velocity head and pressure head) of the fluid as it moves through a fluid system. Head loss is unavoidable in real ...
