Frequently Asked Questions

What is the shape of Cipolletti Weir?

What is Cipolletti weir? A standard Cipolletti weir is trapezoidal in shape. The crest and sides of the weir plate are placed far enough from the bottom and sides of the approach channel to produce full contraction. The sides incline outwardly at a slope of 1 horizontal to 4 vertical.

Is a Cipoletti Weir contracted or suppressed?

(a) Equation for Cipoletti Weirs The Cipoletti weir is a contracted weir. However, its discharge calibration resembles that of a suppressed weir because the effects of side contractions are intentionally compensated for by sloping the sides of the weir plate outward.

How do you calculate the discharge of a Cipolletti Weir?

The Discharge for Cipolletti weir is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass is calculated using discharge = (2/3)* Coefficient of discharge rectangular * sqrt (2* Acceleration Due To Gravity )* Length * Head ^ (3/2).

What is the accuracy of Cipoletti weirs?

The accuracy of measurements obtained by use of Cipoletti weirs and the above equation is considerably less than that obtainable with suppressed rectangular or V-notch weirs (Shen, 1959). The accuracy of the discharge coefficient is + 5 percent.
