Head given Discharge for Cipolletti Weir using Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Still Water Head - (Measured in Meter) - Still Water Head is the head of water which is still over weir.
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.
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

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
Velocity Head: 4.6 Meter --> 4.6 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H_Stillwater = ((Q_C/(1.86*L_w))+H_V^(3/2))^(2/3) --> ((15/(1.86*3))+4.6^(3/2))^(2/3)

Evaluating ... ...

H_Stillwater = 5.4016084227359

STEP 3: Convert Result to Output's Unit

5.4016084227359 Meter --> No Conversion Required

FINAL ANSWER

5.4016084227359 ≈ 5.401608 Meter <-- Still Water Head

(Calculation completed in 00.010 seconds)
