Discharge when End Contractions is suppressed and Velocity is considered Solution

STEP 0: Pre-Calculation Summary

Formula Used

Francis Discharge with Suppressed End = 1.84*Length of Weir Crest*(Still Water Head^(3/2)-Velocity Head^(3/2))
Q_Fr' = 1.84*L_w*(H_Stillwater^(3/2)-H_V^(3/2))
This formula uses 4 Variables

Variables Used

Francis Discharge with Suppressed End - (Measured in Cubic Meter per Second) - Francis Discharge with Suppressed End is discharge of flow without the end contraction.
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_Fr' = 1.84*L_w*(H_Stillwater^(3/2)-H_V^(3/2)) --> 1.84*3*(6.6^(3/2)-4.6^(3/2))

Evaluating ... ...

Q_Fr' = 39.1357298522581

STEP 3: Convert Result to Output's Unit

39.1357298522581 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

39.1357298522581 ≈ 39.13573 Cubic Meter per Second <-- Francis Discharge with Suppressed End

Discharge considering Approach Velocity

LaTeX Go Francis Discharge = (2/3)*Coefficient of Discharge*sqrt(2*Acceleration due to Gravity)*(Length of Weir Crest-0.1*Number of End Contraction*Still Water Head)*(Still Water Head^(3/2)-Velocity Head^(3/2))

Discharge Passing over Weir considering Velocity

LaTeX Go Francis Discharge with Suppressed End = (2/3)*Coefficient of Discharge*sqrt(2*Acceleration due to Gravity)*Length of Weir Crest*((Height of Water above Crest of Weir+Velocity Head)^(3/2)-Velocity Head^(3/2))

Discharge over Weir without considering Velocity

LaTeX Go Francis Discharge with Suppressed End = (2/3)*Coefficient of Discharge*sqrt(2*Acceleration due to Gravity)*Length of Weir Crest*Height of Water above Crest of Weir^(3/2)

Discharge given Velocity Approach

LaTeX Go Discharge by Approach Velocity = Velocity of Flow 1*(Width of Channel1*Depth of Flow)

What is meant by Discharge?

Discharge when End Contractions is Suppressed and Velocity is Considered is defined as a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass.

What is a weir?

A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. They are also used to control the flow of water for outlets of lakes, ponds, and reservoirs.
