Discharge for Cipolletti Weir if Velocity is Considered Solution

STEP 0: Pre-Calculation Summary

Formula Used

Discharge by Cipolletti = 1.86*Length of Weir Crest*(Still Water Head^(3/2)-Velocity Head^(3/2))
Q_C = 1.86*L_w*(H_Stillwater^(3/2)-H_V^(3/2))
This formula uses 4 Variables

Variables Used

Discharge by Cipolletti - (Measured in Cubic Meter per Second) - Discharge by Cipolletti is the rate of flow of a liquid.
Length of Weir Crest - (Measured in Meter) - Length of Weir Crest is the measurement or extent of Weir Crest from end to end.
Still Water Head - (Measured in Meter) - Still Water Head is the head of water which is still over weir.
Velocity Head - (Measured in Meter) - Velocity Head is represented in the term of length unit, also referred to as kinetic head represents the kinetic energy of the fluid.

STEP 1: Convert Input(s) to Base Unit

Length of Weir Crest: 3 Meter --> 3 Meter No Conversion Required
Still Water Head: 6.6 Meter --> 6.6 Meter No Conversion Required
Velocity Head: 4.6 Meter --> 4.6 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_C = 1.86*L_w*(H_Stillwater^(3/2)-H_V^(3/2)) --> 1.86*3*(6.6^(3/2)-4.6^(3/2))

Evaluating ... ...

Q_C = 39.5611182202174

STEP 3: Convert Result to Output's Unit

39.5611182202174 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

39.5611182202174 ≈ 39.56112 Cubic Meter per Second <-- Discharge by Cipolletti

(Calculation completed in 00.020 seconds)

What does Head mean?

Hydraulic head is a specific measurement of liquid pressure above a vertical datum. It is usually measured as a liquid surface elevation.

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.
