Head loss in terms of volumetric flow rate

Description

Hydraulic head or piezometric head is a specific measurement of liquid pressure above a geodetic datum.
In any real moving fluid, energy is dissipated due to friction; turbulence dissipates even more energy for high Reynolds number flows. This dissipation is called head loss. In hydraulic engineering applications, it is often desirable to express the head loss in terms of volumetric flow rate in the pipe.
