An open concrete aqueduct of surface roughness & = 0.01 ft has a rectangular cross section. The aqueduct is 8 ft wide, and falls 7 ft in elevation for each mile of length. It is to carry 100,000 gpm of water at 60 °F. If ff = 0.0049, what is the minimum depth needed if the aqueduct is not to overflow?
