Question

The discharge from weirs without end contractions are measured by

• A. Manning's formula.
• B. Chezy's formula.
• C. Bazin's formula.
• D. Khosla's theory.

Hint:

When calculating discharge in open channels, ensure you have the correct parameters: hydraulic radius, slope, and roughness of the channel.

Answer 1

The Correct Option is A

Manning's formula is the commonly used equation to calculate the discharge through open channels, including weirs without end contractions. It incorporates the channel's roughness, the slope of the flow, and the hydraulic radius.
