Width of Channel given Half Width of Bottom Portion of Weir Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.

STEP 1: Convert Input(s) to Base Unit

Half Width of Bottom Portion of Weir: 29.34 Meter --> 29.34 Meter No Conversion Required
Horizontal Flow Velocity: 10 Meter per Second --> 10 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_c = W_h/(1.467*V_h) --> 29.34/(1.467*10)

Evaluating ... ...

W_c = 2

STEP 3: Convert Result to Output's Unit

2 Meter --> No Conversion Required

FINAL ANSWER

2 Meter <-- Channel Width
