A 42 inch diameter concrete outfall conduit 500 feet long discharges into an estuary. At high tide, the sewer outlet is submerged a depth of 5 feet above invert. If

the beginning invert is at 301.6 ft and the outlet invert is 295.3 fn, determine the capacity and velocity ofthe sewer outfall at high tide when flowing full. Assume n 0,015
