In (a), the water falls freely to the bottom, bounces high because of the large velocity each molecule acquires while falling, and finally settles down to a quiet flow to the right. In (b), the water falls freely only to the first water wheel. The small velocity acquired is imparted to the vanes of the wheel, thereby turning the wheel and causing useful work to be done by whatever is connected with the wheel. The water then falls freely again for a short distance, picking up more velocity, which is imparted to the next wheel. Finally, the

The water then falls freely again for a short distance, picking up more velocity, which is imparted to the next wheel. Finally, the water arrives at the bottom with very little energy to dissipate, so there is little wild bouncing, and the water quickly settles down to its quiet flow to the right.
