The discharge passing over an ogee spillway per unit length of its apex line is proportional ___________________ Correct Answer H3/2

The discharge passing over the ogee spillway is given by the formula – Q = C. Le. H3/2 where Le is the effective length of the spillway crest, C is the coefficient of discharge and H is the total head over the crest including the velocity head. It is clear from the discharge equation that the discharge is proportional to H3/2.

The discharge passing over an ogee spillway is given by (where, L is effective length of spillway crest and H is the total head over the spillway crest including velocity head.)
Statement (I): The ogee spillway is a control weir having an S-shaped crest profile which provides a high discharge coefficient without causing cavitations. Statement (II): The crest profile of ogee spillway conforms to the lower nappe of flow over a ventilated sharp-crested weir and ensures a constant discharge coefficient for all heads.
