Ogee Spillway: Designxls Better

: The Ogee shape is optimized to maintain atmospheric pressure at the design head, preventing cavitation. Excel allows you to quickly iterate through different design heads to find the point where discharge efficiency is maximized.

Q=CLeHe3/2cap Q equals cap C cap L sub e cap H sub e raised to the 3 / 2 power : Discharge coefficient, typically around for ogee crests at design head. Lecap L sub e : Effective length, adjusted for contractions from piers ( Kpcap K sub p ) and abutments ( Kacap K sub a ogee spillway designxls better

Skeptics argue, "Why use a spreadsheet when we have ANSYS Fluent or OpenFOAM?" Lecap L sub e : Effective length, adjusted
