Length of Weir given Flow Diversion Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Weir = (Volume Flow Rate/(3.32*Depth of Flow Over Weir^1.67))^(1/0.83)
L_weir = (Q/(3.32*h^1.67))^(1/0.83)
This formula uses 3 Variables

Variables Used

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.
Volume Flow Rate - (Measured in Cubic Meter per Second) - Volume Flow Rate is the volume of fluid that passes per unit of time.
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

Volume Flow Rate: 1.5 Cubic Meter per Second --> 1.5 Cubic Meter per Second 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

L_weir = (Q/(3.32*h^1.67))^(1/0.83) --> (1.5/(3.32*0.8^1.67))^(1/0.83)

Evaluating ... ...

L_weir = 0.601545594728978

STEP 3: Convert Result to Output's Unit

0.601545594728978 Meter --> No Conversion Required

FINAL ANSWER

0.601545594728978 ≈ 0.601546 Meter <-- Length of Weir
