The Eifel aqueduct was built in 80 AD to provide water to present-day city of Cologne. As one of the longest aqueducts of the Roman Empire, it transports water 95 kilometers relying only on gravity to produce flow (with a 1 meter drop in elevation per kilometer). The water flows through a rectangular channel with an open top. The channel is 70 cm wide, and water reaches an average depth of 1 meter. The material used in its construction can be considered equivalent to rough concrete. At what rate (m3/s) is water being supplied to Cologne?
