WebSep 12, 2024 · Flow rate and velocity are related, but quite different, physical quantities. To make the distinction clear, consider the flow rate of a river. The greater the velocity of the water, the greater the flow rate of the river. But flow rate also depends on the size and shape of the river. A rapid mountain stream carries far less water than the ... WebSep 22, 2024 · 1038. 1482. Flow Rate (GPM) at a given velocity & line size. In summary, flow rate is the amount of volume that passes through an area during a given period of time. Flow velocity, or speed, depends on the size on the container the fluid is moving …
WebVelocity is the distance an object (solid, liquid or gas) moves with respect to time (i.e., the distance traveled per unit of time). With blood flowing in a vessel, velocity is often … WebFigure 1. Flow rate is the volume of fluid per unit time flowing past a point through the area A. Here the shaded cylinder of fluid flows past point P in a uniform pipe in time t. The …
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 ...
