### Head Loss | Engineering Library

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 fluids. It is present because of: the friction between the fluid and the walls of the pipe; the friction between adjacent fluid particles as they move relative to one another; and the turbulence caused whenever the flow is redirected or affected in any way by such components as piping entrances and exits, pumps, valves, floSee more on engineeringlibrary.orgFully developed pipe flow with heat transfer - QuickerSimMar 07, 2018 · **Heat** transfer in a laminar **pipe flow**.
