Pressure at a given point in a water system when no water is flowing?

Pressure at a given point in a water system when no water is flowing?

• A. Static Pressure
• B. Residual Pressure
• C. Gate Valve
• D. Steamer Connection

Answer: (A)

Static pressure is the pressure in a water system at a point when no water is moving. This is the baseline pressure provided by the source, since there is no flow to cause friction losses or dynamic pressure changes. When water is flowing, the pressure drops due to friction and other losses, and that lower value is called residual pressure. The other options refer to hardware or a condition that describes pressure during flow, not the situation with no movement. So the pressure at a point with no flow is static pressure.
