A landscape architect is planing an artificial water fall. Water flowing at 1.11 m/s will leave the end of a horizontal channel at the top of a vertical wall h=4.00 m high. Will the space behind the waterfall be wide enough for a pedistrian walkway?
b. To sell her plan to the city council, the architect wants to build a model to scale, which is 1/14 actual size. How fast should the water flow in the channel in the model?
