WebThe effective coefficient of discharge for flow nozzles in pipelines varies from 0.96 to 1.2 for turbulent flow and increases as the throat-to-pipe-diameter ratio increases. Frequently, the upstream pressure connection is made through a hole in the wall of the conduit at a distance of about one pipe diameter upstream from the starting point of the flare of the … WebThe most efficient nozzle is generally considered to be that for which the discharge coefficient is nearest unity. Forms and dimensions of the nozzles being equal, the greater the discharge coefficient, the less the jet turbulence becomes. The inefficiency of fire streams is directly attributable to the inital turbulence of the jet and this turbulence has its …
