The discharge through a trapezoidal channel is maximum when
The discharge through a trapezoidal channel is maximum when
Show Hint
For the most efficient channel design:
- Trapezoidal: Sloping side = Half of top width. This simplifies to \(b = 2d\tan(\theta/2)\).
- Rectangular: Bed width is twice the depth of flow (\(b = 2d\)).
- Trapezoidal: Sloping side = Half of top width. This simplifies to \(b = 2d\tan(\theta/2)\).
- Rectangular: Bed width is twice the depth of flow (\(b = 2d\)).

- $b = 2d \tan \theta/2$
- $d = 2b \tan \theta/2$
- $d = 2b$
- $b = 2d$
