An incompressible fluid is in streamline flow through a Venturi meter, as shown. In the graph, one of the curves is a calibration curve for the meter, showing the fluid velocity plotted against the gauge reading. Which curve best represents the calibration data?

Question

Quizplus · Accepted Answer

The curve that best represents the calibration data is the one that shows a linear relationship between fluid velocity and gauge reading. The curve labelled 2 shows such a relationship and is, therefore, the best choice. The other curves show either non-linear or inconsistent relationships between velocity and gauge reading.
