Generated explanation

A schematic house section shows a water supply pipe entering from the city water supply and running horizontally beneath the floor to two plumbing fixtures. Vertical branches connect the horizontal supply pipe to the fixture faucets, including a labeled basin on the right. Three callouts indicate 60 psi static pressure at points along the supply pipe at the same elevation. The illustration explains that, when no water is flowing, static pressure is the same at all points along the pipe that are at the same elevation.
