What is static head?

What is static head?

• A. The total equivalent height that a pump lifts water, including friction loss
• B. Friction loss
• C. The vertical distance between a reference point to the water surface, when the water is not moving
• D. The horizontal distance between a reference point to the water

Answer: (C)

Static head refers to the vertical distance between a reference point, such as the bottom of a tank or a pump, and the surface of the water when the water is at rest and not moving. This measurement is crucial in water distribution systems as it represents the potential energy available in the water due to gravity. Understanding static head is essential for operators as it helps in determining the capabilities of pumps and the overall hydraulic design of water distribution systems. In this context, the choice identifies the specific measurement that reflects the static condition of the water, providing insight into how much pressure can be exerted if the water were to flow. By recognizing that static head is independent of motion, it differentiates itself from concepts that involve dynamic conditions or energy losses, like friction loss or the energy a pump must exert to overcome resistance in the system.
