Hydraulic head, abbreviated as h, is the measurement mechanical energy due to pressure of a fluid from a higher elevation to a lower elevation.

### Hydraulic Head Formula

$$\large{ h = \frac {p}{g \; \rho} }$$

Where:

$$\large{ h }$$= head

$$\large{ \rho }$$   (Greek symbol rho) = density

$$\large{ g }$$ = gravitational acceleration

$$\large{ p }$$ = pressure
