Laminar flow or streamline flow occurs at relatively low speeds.When water flows through a cylindrical pipe it flows in layers: several concentric cylinders from the central axis to the layer in contact with the pipe.
The water in the central axis will have the fastest velocity as it experiences the least friction from the other layers.Layers do not mix.The velocity of each layer increases near the centre and is least in the layer in contact with the pipe.
