Discharge Over weirs MCQs : This section focuses on the "Discharge Over weirs". These Multiple Choice Questions (MCQs) should be practiced to improve the Discharge Over weirs skills required for various interviews (campus interview, walk-in interview, company interview), placement, entrance exam and other competitive examinations.

B. 2.5 m3/s
C. 3.1 m3/s
D. 3.3 m3/s
Question 2
An Ogee weir 5 m long had a head of 40 cm of water. If CD = 0.61, find the discharge over the weir.
A. 2.9 m3/s
B. 2.3 m3/s
C. 3.1 m3/s
D. 3.3 m3/s
