WebApr 6, 2024 · The fluid velocity in a pipe is a function of the flow rate and the pipe’s area. Given a flowrate, a larger pipe will have a lower velocity, and a small pipe will have a higher velocity. This concept is critical to understanding the hydraulics of pipeline design because friction and turbulence are mostly a result of flow velocity. WebFeb 20, 2024 · Flow rate and velocity are related, but quite different, physical quantities. To make the distinction clear, think about the flow rate of a river. The greater the velocity of the water, the greater the flow rate of the river.
