What is 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.
In the analysis of piping systems, pressure losses are commonly expressed in terms of the equivalent fluid column height, called the head loss. Noting from fluid statics that ΔP = 𝜌gh and thus a pressure difference of ΔP corresponds to a fluid height of h = ΔP/𝜌g.
The head loss represents the additional height that the fluid needs to be raised by a pump in order to overcome the frictional losses in the pipe. The head loss is caused by viscosity, and it is directly related to the wall shear stress.
