A landscape architect is planning an artificial waterfall in a city park. Water flowing at 0.518 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.55 m high and falls into a pool (see figure). (b) To sell her plan to the city council, the architect wants to build a model to standard scale, one-seventeenth actual size. How fast should the water flow in the channel in the model?
