What is static pressure?

Static pressure refers to the pressure exerted by a fluid at rest. In the context of irrigation, it is the pressure of water in a system when no water is flowing. This concept is crucial for understanding the hydraulic conditions within the irrigation system, as it helps determine how well water can be delivered to various parts of the system when the system is not in operation.

Understanding static pressure is important for the design and operation of irrigation systems, as it affects the selection of pumps, the layout of the distribution network, and the overall efficiency of water delivery. Static pressure can provide insights into the potential for water delivery under various conditions, such as changes in elevation and friction loss in pipes.

In contrast, the other options relate to different aspects of pressure or water characteristics that do not accurately define static pressure.
