Standard Test Method for Open Channel Flow Measurement of Water with the Parshall Flume
|Publication Date:||15 June 2007|
|ICS Code (Sewage water):||13.060.30|
significance And Use:
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) (1) and (2)4 .... View More
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) (1) and (2)4 . They can therefore be applied to a wide range of flows, with head losses that are moderate.
The flume is self-cleansing for moderate solids transport and therefore is suited for wastewater and flows with sediment.View Less
