Head given Discharge over Cipolletti Weir Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.

STEP 1: Convert Input(s) to Base Unit

Discharge by Cipolletti: 15 Cubic Meter per Second --> 15 Cubic Meter per Second No Conversion Required
Length of Weir Crest: 3 Meter --> 3 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

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

Evaluating ... ...

S_w = 1.93332428713651

STEP 3: Convert Result to Output's Unit

1.93332428713651 Meter --> No Conversion Required

FINAL ANSWER

1.93332428713651 ≈ 1.933324 Meter <-- Height of Water above Crest of Weir

(Calculation completed in 00.004 seconds)
