Web30 de out. de 2024 · If you want your flume to be as accurate as possible, you should pick a flume with a long throat instead of a short-throated section. Flumes with longer throats tend to be much more accurate than their short-throated counterparts. You also need to keep in mind the risk of experiencing submergence conditions, which can decrease the …
Web1 de set. de 1977 · Because a broad-crested weir with rounded upstream nose behaves in the same hydraulic manner as a long- throated flume, all equations in this paper also apply to that type of weir (Bos, 1976). If a long-throated flume is to function as an accurate discharge measuring device, flow in the flume throat must be critical (y = Yc). WebU-flumes are a subset of long-throated flumes suitable for use in wastewater metering. Although their mathematical characteristics are well defined so that they can be readily …
