What is the condition for maximum velocity of flow through a circular channel section of diameter 'd' and radius 'R' (where θ is the half-central angle)?
- 1Depth of flow h = 0.81d; Area of flow = R2/2 · (2θ - sin θ)
- 2Depth of flow h = 0.81d; Area of flow = R2/2 · (2θ - sin 2θ)✓
- 3Depth of flow h = 0.81d; Area of flow = R2/2 · (2 - sin 2θ)
- 4Depth of flow h = 0.81d; Area of flow = R2/2 · (θ - sin 2θ)
Correct answer
Depth of flow h = 0.81d; Area of flow = R2/2 · (2θ - sin 2θ)
