-Imagine dropping of bit of ink into the fluid and let it flow for a while. This will result in a line that shows the path a ink particle has taken. Such a path is called a streamline. A streamtube is a 3D variant of a streamline. It consists of a number of consecutive tubes that together form a thick 3-dimensional tube. \\
