2-inch Parshall Flume
Description:
One of the small Parshall flume sizes developed in 1960 at the Colorado Agricultural Experiment Station, the 2-inch Parshall flume is commonly used to measure water flowing in creeks, furrows, irrigation canals, and channels.
Galvanized steel flumes shouldn't be used to measure sanitary flows.
Material of Construction:
- Galvanized steel
Flow Rates:
- 0.0065 - 0.4783 cfs (cubic feet / second)
- 2.920 - 214.7 gpm (US gallons / minute)
- 0.0042 - 0.3092 mgd (US million gallons / day)
Flow Accuracy:
- +/- 2-5% (ASTM D1941)
Flow Formula (H = feet):
- Q (cfs) = 0.676 * H^1.55
- Q (gpm) = 303.4 * H^1.55
- Q (mgd) = 0.4359 * H^1.55
