Length of Crest given Discharge over Cipolletti Weir by Francis, Cipolletti Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Weir Crest = Discharge by Cipolletti/(1.86*Height of Water above Crest of Weir^(3/2))
L_w = Q_C/(1.86*S_w^(3/2))
This formula uses 3 Variables

Variables Used

Length of Weir Crest - (Measured in Meter) - Length of Weir Crest is the measurement or extent of Weir Crest from end to end.
Discharge by Cipolletti - (Measured in Cubic Meter per Second) - Discharge by Cipolletti is the rate of flow of a liquid.
Height of Water above Crest of Weir - (Measured in Meter) - Height of Water above Crest of Weir is defined as the water surface height above crest.

STEP 1: Convert Input(s) to Base Unit

Discharge by Cipolletti: 15 Cubic Meter per Second --> 15 Cubic Meter per Second No Conversion Required
Height of Water above Crest of Weir: 2 Meter --> 2 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_w = Q_C/(1.86*S_w^(3/2)) --> 15/(1.86*2^(3/2))

Evaluating ... ...

L_w = 2.8512370209135

STEP 3: Convert Result to Output's Unit

2.8512370209135 Meter --> No Conversion Required

FINAL ANSWER

2.8512370209135 ≈ 2.851237 Meter <-- Length of Weir Crest

(Calculation completed in 00.020 seconds)

What does head mean?

Hydraulic head is a specific measurement of water pressure or total energy per unit weight above a datum.

What is Cipolletti weir?

A standard Cipoletti 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.
