A coconut farmer is entertaining the idea of establishing a vertical-drop water wheel to power a coconut dehusker. To divert water from a nearby river, he also need to build an open rectangular canal 1 m wide and 0.75 m deep. The stream depth in the canal will be maintained at 0.50 m to have a 2.50 m/s stream flow. If the coconut dehusker needs a 10 kW power input, how far below the canal should the water wheel be positioned for the falling water to hit it tangentially? Assume a water wheel efficiency of 50%.

Question
A coconut farmer is entertaining the idea of establishing a vertical-drop water wheel to power a coconut dehusker. To divert water from a nearby river, he also need to build an
open rectangular canal 1 m wide and 0.75 m deep. The stream depth in the canal will be
maintained at 0.50 m to have a 2.50 m/s stream flow. If the coconut dehusker needs a 10
kW power input, how far below the canal should the water wheel be positioned for the
falling water to hit it tangentially? Assume a water wheel efficiency of 50%.
