Head is a measurement of the energy that water has at any particular location in the water system. This article discusses three types of head, pressure head, elevation head, and velocity head. Pressure head is a measurement of the amount of energy in water due to water pressure. Elevation head is a measurement of the amount of energy that water possesses because of its elevation. Velocity head is a measurement of the amount of energy in water due to its velocity, or motion. Of the three types of head discussed, pressure head is the most significant and useful to the operator. Examples are provided which illustrate how pressure heads can be measured and calculated.
