Analogs To Other Fields
Hydraulic head is a measure of energy, and has many analogs in physics and chemistry, where the same mathematical principles and rules apply:
- Hydraulic head is analogous to:
- magnetic monopole
- electric charge
- heat (i.e., temperature)
- concentration
- A continuous "field" of hydraulic heads is analogous to:
- an electric field
- a magnetic field
- Similar differential operators can be applied to the fields, to find:
- the gradient, or the direction of flow
- the divergence of flow
- the curl, or if the field is rotating

Famous quotes containing the word fields:
“On fields all drenched with blood he made his record in war, abstained from lawless violence when left on the plantation, and received his freedom in peace with moderation. But he holds in this Republic the position of an alien race among a people impatient of a rival. And in the eyes of some it seems that no valor redeems him, no social advancement nor individual development wipes off the ban which clings to him.”
—Frances Ellen Watkins Harper (1825–1911)
