Discharge through Drowned Portion given Total Discharge over Submerged Weir Solution

STEP 0: Pre-Calculation Summary

Formula Used

Discharge through Drowned Portion = Total Discharge of Submerged Weir-Discharge through Free Portion
Q₂ = Q_T-Q₁
This formula uses 3 Variables

Variables Used

Discharge through Drowned Portion - (Measured in Cubic Meter per Second) - Discharge through Drowned Portion is a measure of the quantity of fluid flow over unit time, representing the quantity of water in between the downstream and the crest of the water.
Total Discharge of Submerged Weir - (Measured in Cubic Meter per Second) - Total Discharge of Submerged Weir is sum of the discharge from free and drowned portion.
Discharge through Free Portion - (Measured in Cubic Meter per Second) - Discharge through Free Portion is a measure of the quantity of fluid flow over unit time, representing the quantity in between the upstream and downstream portion.

STEP 1: Convert Input(s) to Base Unit

Total Discharge of Submerged Weir: 174.7 Cubic Meter per Second --> 174.7 Cubic Meter per Second No Conversion Required
Discharge through Free Portion: 50.1 Cubic Meter per Second --> 50.1 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q₂ = Q_T-Q₁ --> 174.7-50.1

Evaluating ... ...

Q₂ = 124.6

STEP 3: Convert Result to Output's Unit

124.6 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

124.6 Cubic Meter per Second <-- Discharge through Drowned Portion

(Calculation completed in 00.004 seconds)

Coefficient of Discharge given Discharge through Free Weir Portion

LaTeX Go Coefficient of Discharge = (3*Discharge through Free Portion)/(2*Length of Weir Crest*sqrt(2*Acceleration due to Gravity)*(Head on Upstream of Weir-Head on Downstream of Weir)^(3/2))

Head on Upstream Weir given Discharge through Free Weir Portion

LaTeX Go Head on Upstream of Weir = ((3*Discharge through Free Portion)/(2*Coefficient of Discharge*Length of Weir Crest*sqrt(2*Acceleration due to Gravity)))^(2/3)+Head on Downstream of Weir

Length of Crest for Discharge through Free Weir Portion

LaTeX Go Length of Weir Crest = (3*Discharge through Free Portion)/(2*Coefficient of Discharge*sqrt(2*Acceleration due to Gravity)*(Head on Upstream of Weir-Head on Downstream of Weir)^(3/2))

Discharge through Free Weir Portion

LaTeX Go Discharge through Free Portion = (2/3)*Coefficient of Discharge*Length of Weir Crest*sqrt(2*Acceleration due to Gravity)*(Head on Upstream of Weir-Head on Downstream of Weir)^(3/2)
