9-inch Parshall Flume
Description:
The 9-inch Parshall flume is useful in measuring a range of different flows. Water right and surface waters are common applications for 9-inch Parshall flumes, but spring discharges and edge-of-field flow are also applications for the flume.
Galvanized Parshall flumes should never be used on sanitary flows.
Material of Construction:
- Galvanized steel
Flow Rates:
- 0.0906 - 8.866 cfs (cubic feet / second)
- 40.66 - 3,979 gpm (US gallons / minute)
- 0.0586 - 5.730 mgd (US million gallons / day)
Flow Accuracy:
- +/- 2-5% (ASTM D1941)
Flow Formula (H = feet):
- Q (cfs) = 3.07 * H^1.53
- Q (gpm) = 1,378 * H^1.53
- Q (mgd) = 1.984 * H^1.53
