The typical discharge coefficient is approximately for free flow conditions and depth ratios < 0.2. The unit-width discharge under a rectangular sluice gate is q = v2 y2, where the contraction coefficient Cc varies within a narrow range, between 0.598 and 0.611. A value of Cc = 0.61 has been recommended for practical use. The conventional sluice-gate discharge equation is Q = C.abVWo, where Cd is the discharge coefficient.
