A smooth concrete pipe (1.5 ft diameter) carries water from a reservoir to an industrial treatment plant 1.0 mile away and discharges it into the air over a holding tank. The pipe leaving the reservoir is 3 ft below the water surface and runs downhill on a 1:100 slope. Determine the flow rate (in ft3/sec) if the water temperature is 40°F (4°C) and minor losses are negligible. USE COLEBROOK-WHITE EQUATION
