Residual pressure correct answers The portion of the total available pressure not used to overcome friction loss or gravity or forcing water through pipes, fittings, hoses, or adapters *remainder Static pressure correct answers Stored potential energy available to force water through pipes, fittings, hose, and adapters Head pressure correct answers The height of a water supply above the discharge orifice Static correct answers Rest, or without motion Atmospheric pressure at sea level correct answers 14.7 psi Normal operating pressure correct answers Pressure found in a water distribution system during normal consumption demands. Flow pressure/velocity pressure correct answers forward velocity pressure while water is flowing Distribution system correct answers The overall water supply system receives the water from the pumping station and delivers it throughout the area served Dead-End Hydrant correct answers Receives water from only one direction Circulating feed or looped line correct answers Hydrant receives water from two or more directions Grid system correct answers System that provides circulating feed from several mains Primary feeder correct answers - large pipes (mains) with relatively widespread spacing that convey large quantities of water to various points of the system for local distribution to smaller mains. Secondary feeders correct answers Network of intermediate sized mains that subdivide the grid within the primary feeders Distributor correct answers Grid arrangement of smaller mains serving individual fire hydrants and blocks of consumers First principle of friction loss correct answers If all other conditions are the same, friction loss varies directly with the length of the hose or pipe Second principle of friction loss correct answers When hoses are the same size, friction loss varies approximately with the square of the increase in the velocity of the flow
