WebSep 26, 2010 · • Mean velocity – Weighted average of all flow velocities across the pipe diameter. • Sensed velocity – The velocity that is measured by the flowmeter. Figure 1. To determine a flow profile, instrument engineers divide the pipe cross-section into several concentric annular areas. Webis the cross-sectional area of the portion of the channel occupied by the flow ( [L 2 ]; m 2 or ft 2) is the average flow velocity ( [LT −1 ]; m/s or ft/s) For example, the average discharge of the Rhine river in Europe is 2,200 cubic metres per second (78,000 cu ft/s) or 190,000,000 cubic metres (150,000 acre⋅ft) per day.
