WebIn steady flow, the fluid passing a given point maintains a steady velocity. For turbulent flow, the speed and or the direction of the flow varies. In steady flow, the motion can be represented with streamlines showing the direction the water flows in different areas. The density of the streamlines increases as the velocity increases. WebFlow is different than velocity. Velocity is defined as the distance a given fluid moves within a unit of time, most commonly expressed in centimeters per second. The flow of a fluid within a tube is related to velocity by the relationship F = V ⋅ r 2, where V is the mean velocity and r is the radius of the tube. + + + WebApr 6, 2024 · We expect the pressure drop to be 1 over (⅔)^4.9 or about 7 times higher than the original pipe. At 0.3 gpm, the pressure drop is 3 inches. That’s about 6 times the original. At 0.6 gpm, the pressure drop is 7.5 inches, about 7 times the original. And at 0.9 gpm, we’re off the scale. northeastern khoury college
