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 ... WebApr 14, 2024 · The concentration of DIN showed a significant correlation (r = 0.72, p <0.001) against the river water discharge, indicating that the river-derived DIN is a main source of DIN in this estuary, and that DIN is quite conservative in this river water-seawater mixing zone ().The average DIN concentration in the fresh river water (salinity <2) during large …
