36-inch Parshall Flume
Description:
36-inch Parshall flumes are useful when flow are higher or channels are wider. They are used to measure water rights / irrigation flows as well as surface waters.
Galvanized steel should never be used to measure sanitary flows.
Material of Construction:
- Galvanized steel
Flow Rates:
- 0.6151 - 50.39 cfs (cubic feet / second)
- 276.1 - 22,616 gpm (US gallons / minute)
- 0.3975 - 32.57 mgd (US million gallons / day)
Flow Accuracy:
- +/- 2-5% (ASTM D1941)
Flow Formula (H = feet):
- Q (cfs) = 12 * H^1.566
- Q (gpm) = 5,386 * H^1.566
- Q (mgd) = 7.756 * H^1.566
