Parshall Flume Flow Chart

Parshall Flume Flow Chart - The parshall flume is constructed with a converging upstream section, a throat, and a diverging downstream section. In accordance with iso 9826, parshall flumes are designed for measurement of volumetric flow rate in rectangular channels with gravity flow. Web flow chart for 18” parshall flume. The flume in cfs, ha is the head over the flume in ft (measured at the point shown for ha in the diagram above), and c and n are constants for a parshall flume of given throat width. 0.16 0.56 2.101 3.2567 1,461.6 0.17 0.57. The parshall flume is a modified version of the venturi flume. As parshall flumes increase in size, their resistance to the effects of downstream submergence increases. With the above known, the flow rate in the flume can now be calculated. Head (feet) mgd cfs gpm head (feet) mgd cfs gpm. The point of measurement in a parshall flume is located.
