Question

Quizplus · Accepted Answer

The average velocity of water in a stream is an approximation that accounts for friction and turbulence. It is not simply the velocity at the surface of the stream or in the inside of curves in the stream's path. It is also not the velocity at which all of the water is moving, as there may be variation in velocity throughout different parts of the stream.
