Flow Diversion for Side Weir Solution

STEP 0: Pre-Calculation Summary

Formula Used

Volume Flow Rate = 3.32*Length of Weir^(0.83)*Depth of Flow Over Weir^(1.67)
Q = 3.32*L_weir^(0.83)*h^(1.67)
This formula uses 3 Variables

Variables Used

Volume Flow Rate - (Measured in Cubic Meter per Second) - Volume Flow Rate is the volume of fluid that passes per unit of time.
Length of Weir - (Measured in Meter) - Length of Weir is defined as the total length of the weir calculated when the flow rate of the diversion weir is given.
Depth of Flow Over Weir - (Measured in Meter) - Depth of Flow Over Weir is the total depth of flow over the weir at down-stream end.

STEP 1: Convert Input(s) to Base Unit

Length of Weir: 0.6 Meter --> 0.6 Meter No Conversion Required
Depth of Flow Over Weir: 0.8 Meter --> 0.8 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = 3.32*L_weir^(0.83)*h^(1.67) --> 3.32*0.6^(0.83)*0.8^(1.67)

Evaluating ... ...

Q = 1.49680043187199

STEP 3: Convert Result to Output's Unit

1.49680043187199 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

1.49680043187199 ≈ 1.4968 Cubic Meter per Second <-- Volume Flow Rate

FAQ

What is Flow Diversion for Side Weir?

The Flow diversion for side weir formula is defined as the flow which takes place in a diversion weir. A diversion weir is a low obstruction that is built across a river or canal to raise the water level, or in parallel to divert the water and is represented as Q = 3.32*L_weir^(0.83)*h^(1.67) or Volume Flow Rate = 3.32*Length of Weir^(0.83)*Depth of Flow Over Weir^(1.67). Length of Weir is defined as the total length of the weir calculated when the flow rate of the diversion weir is given & Depth of Flow Over Weir is the total depth of flow over the weir at down-stream end.

How to calculate Flow Diversion for Side Weir?

The Flow diversion for side weir formula is defined as the flow which takes place in a diversion weir. A diversion weir is a low obstruction that is built across a river or canal to raise the water level, or in parallel to divert the water is calculated using Volume Flow Rate = 3.32*Length of Weir^(0.83)*Depth of Flow Over Weir^(1.67). To calculate Flow Diversion for Side Weir, you need Length of Weir (L_weir) & Depth of Flow Over Weir (h). With our tool, you need to enter the respective value for Length of Weir & Depth of Flow Over Weir and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Volume Flow Rate?

In this formula, Volume Flow Rate uses Length of Weir & Depth of Flow Over Weir. We can use 1 other way(s) to calculate the same, which is/are as follows -

Volume Flow Rate = Area for Siphon Throat*Coefficient of Discharge*(2*Acceleration due to Gravity*Head of Liquid)^(1/2)
