Question

Need help with fluid mechanic problem.

A pair of sluice gates in a dam are lifted half its height to allow draw down of the pond.  The gates each measure 2.5 feet wide by 2.5 feet high. The water surface elevation of the impoundment is 6 feet above the bottom of the gate opening.  If the discharge coefficient, c, for the gates are 0.66, compute the discharge.
