Head (Fluid Pressure Measurement)

In plumbing and fluid dynamics, “head” refers to the pressure of water or steam in a closed system, expressed in terms of the height of a fluid column that the pressure can support. It is a critical parameter in designing water supply systems, pumps, and heating systems, as it determines the capacity to move water to different elevations or overcome system resistance. Head is measured in feet or meters and is used to assess pump performance, flow rates, and system efficiency. There are different types of head, such as static head, dynamic head, and total head, each representing specific pressure conditions in the system. Understanding head is essential for ensuring that plumbing systems are designed to deliver adequate pressure to all fixtures and prevent issues like insufficient flow or pressure loss.
