Webb5 mars 2024 · 5.7: Gradually Varied Flow. Nonuniform flows for which the changes in depth and velocity are so abrupt that radial accelerations distort the vertical distribution of fluid pressure from the hydrostatic condition are called rapidly varied flows. Flow over a sharp-crested dam or weir, and flow under a sluice gate, are good examples. Webb16 apr. 2024 · The size of x is the value by which the sluice gates are constantly immersed in the water. In that way (in the plane in which the measurements were performed), the level of water in the chambers is reduced to the value hx − x. The widths of the chambers are 3.20, 3.06, and 3.16 m, respectively. Webb1: Tube connecting the chamber to the high water side of the sluice 2: Gates to regulate the water level in the chamber.
