A reservoir discharges into a 6-inch diameter galvanized iron pipe which discharges freely at a point 5,000 feet from the reservoir. The elevation of the water surface in the reservoir is 615.0 feet and the invert of the pipe at the discharge is 602.0 feet. Find the velocity and the discharge in the pipe. Consider friction but neglect minor losses.
