A standard suppressed rectangular weir has a horizontal crest that crosses the full channel width.

According to Francis formula, the discharge over a rectangular weir is (where n = Number of end contractions)

A. (2/3) × Cd (L - nH) × √(2gh)

B. (2/3) × Cd (L - 0.1nH) × √(2g) × H3/2

C. (2/3) × Cd (L - nH) × √(2g) × H²

D. (2/3) × Cd (L - nH) × √(2g) × H5/2
