Question

A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.65 m high, and from there the water falls into a pool (see figure).

(a) Will the space behind the waterfall be wide enough for a pedestrian walkway?

YesNo    

(b) To sell her plan to the city council, the architect wants to build a model to a scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model?
