Q1: Discharge over an ogee weir remains the same as that of

ANS:C - cippoletti weir

The discharge over an ogee weir is not the same as that of other types of weirs. However, it's worth noting that the discharge over an ogee weir may be comparable to that of a sharp crested weir under certain conditions. An ogee weir is designed with a smooth curve on the downstream side, providing a more gradual transition of water flow over the weir compared to sharp crested weirs. This design aims to reduce flow disturbances and improve flow characteristics. The discharge over an ogee weir is generally different from that of a sharp crested weir, triangular weir, cippoletti weir, or drowned weir. Each type of weir has its specific flow characteristics and equations governing the discharge. The discharge over a sharp crested weir, for instance, is governed by different equations compared to an ogee weir. Similarly, triangular, cippoletti, and drowned weirs each have their unique flow equations and discharge characteristics. Therefore, the statement that the discharge over an ogee weir remains the same as that of a sharp crested weir, triangular weir, cippoletti weir, or drowned weir is generally incorrect. Each type of weir has its own hydraulic characteristics and equations governing discharge.
