Solution
A flow is said to be one-, two-, or three-dimensional if the flow velocity varies in one, two, or three primary dimensions, respectively. This means that the flow's direction and speed are only changing in a certain number of spatial dimensions. For example, in a one-dimensional flow, the velocity only changes along one spatial dimension, such as along the length of a pipe. In a two-dimensional flow, the velocity might change both along the length and across the width of a channel. In a three-dimensional flow, the velocity could change in any direction within a volume of fluid.
