A reservoir of water is connected to 8-inch-diameter pipe 50 feet long and discharging freely. The water surface elevation of the reservoir is 410.0, and the elevation of the center of the pipe at its discharge end is 372.5. Neglecting friction, determine the velocity, v, and discharge, Q, at the end of the pipe.
