Half Width of Bottom Portion of Weir Solution

STEP 0: Pre-Calculation Summary

Formula Used

Half Width of Bottom Portion of Weir = 1.467*Horizontal Flow Velocity*Channel Width
W_h = 1.467*V_h*W_c
This formula uses 3 Variables

Variables Used

Half Width of Bottom Portion of Weir - (Measured in Meter) - Half Width of Bottom Portion of Weir is half of the total width at the bottom section of a weir. A weir is a barrier built across a river or stream to alter its flow characteristics.
Horizontal Flow Velocity - (Measured in Meter per Second) - Horizontal Flow Velocity is the velocity for which the weir is designed.
Channel Width - (Measured in Meter) - Channel Width is the horizontal distance between the banks of a channel, measured at right angles to the direction of flow.

STEP 1: Convert Input(s) to Base Unit

Horizontal Flow Velocity: 10 Meter per Second --> 10 Meter per Second No Conversion Required
Channel Width: 2 Meter --> 2 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_h = 1.467*V_h*W_c --> 1.467*10*2

Evaluating ... ...

W_h = 29.34

STEP 3: Convert Result to Output's Unit

29.34 Meter --> No Conversion Required

FINAL ANSWER

29.34 Meter <-- Half Width of Bottom Portion of Weir

(Calculation completed in 00.020 seconds)
