In continuum mechanics the flow velocity in fluid dynamics, also macroscopic velocity in statistical mechanics, or drift velocity in electromagnetism, is a vector field used to mathematically describe the motion of a continuum. The length of the flow velocity vector is the flow speed and is a scalar. It is also called velocity field; when evaluated along a line, it is called a velocity profile (as in, e.g., law of the wall). WebFeb 27, 2024 · What happens as a pipe is lengthened is that its flow resistance increases in direct proportion to its length. In practice, the effect of that increased flow resistance depends on whether the pipe flow is being driven by a constant pressure pump or a constant flow (i.e., positive displacement) pump. For example, if the pipe is driven by a ...
