Head loss in terms of volumetric flow rate
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.
|V||Average velocity of the fluid flow (m/s)|
|Q||Volumetric flow rate (m3/s)|
|Aw||Cross-sectional wetted area (m2)|
