Significance and Use | ||||||||
5.1?Flume designs are available for throat sizes of 1 in. (2.54 cm) to 50 ft (15.2 m) which cover maximum flows of 0.2 to 3000 ft3/s (0.0057 to 85 m3/s) 5.2?The flume is self-cleansing for moderate solids transport and therefore is suited for wastewater and flows with sediment. |
